Board: Central of Secondary Education
Class: Class 6
Subject: Maths
Chapter Name: Knowing Our Numbers

Comparing Numbers :
As we have done quite a lot of this earlier, let us see if we

Knowing Our Numbers Class 6 Maths 1

How many numbers can we make?
Suppose, we have four digits 1, 2, 3, 4. Using these digits we want to make different 4-digit numbers such that no digits are repeated in a number. Thus, 3241 is allowed but 1123 is not. The greatest number is 4321 and the smallest is 1234.
Ex: Use the given digits without repetition and make the greatest and smallest 4-digit numbers.
(a) 2, 8, 6, 1
(b) 3, 0, 7, 4
(c) 8, 9, 2, 3
(d) 5, 0, 8, 2
Sol:
(a) Greatest number is 8621, Smallest number is 1268
(b) Greatest number is 7430, Smallest number is 3047
(c) Greatest number is 9832, Smallest number is 2389
(d) Greatest number is 8520, Smallest number is 2058

Ascending order:
Ascending order means arrangement from the smallest to the greatest.
Ex. 847, 9754, 8320, 571
Sol. 571, 847, 8320, 9754

Descending order:
Descending order means arrangement from the greatest to the smallest.
Ex. 847, 9754, 8320, 571
Sol. 9754, 8320, 847, 571

Introducing 10,000:
We observe that :
Greatest single digit number+1 = smallest 2-digit number
9 + 1 = 10
Greatest 2-digit number + 1 = smallest 3-digit number
99 + 1 = 100
Greatest 3-digit number + 1 = smallest 4-digit number
999 + 1 = 1000
Greatest 4-digit number + 1 = smallest 5-digit number
9999 + 1 = 10,000
Knowing Our Numbers Class 6 Maths 2

Remember :
1 hundred = 10 tens
1 thousand = 10 hundreds = 100 tens
1 lakh = 100 thousands = 1000 hundreds
1 crore = 100 lakhs = 10,000 thousands

Use of Commas:
1. Indian System of Numeration: In our Indian System of Numeration we use one, tens, hundreds, thousands and then lakhs and crores. The first comma comes after hundreds place (three digits from the right) and marks thousands. The second comma comes two digits later (five digits from the right). It comes after ten thousands place and marks lakh. The third comma comes after another two digits (seven digits from the right). It comes after ten lakh place and marks crore.
For example, 5, 78, 21, 623

2. International System of Numeration: In the International System of Numeration, as it is being used we have ones, tens, hundreds, thousands and then millions. One million is a thousand thousands. Commas are used to mark thousands and million. It comes after every three digits from the right. The first comma mark thousands and the
next comma marks millions.
For example, 57, 821, 623

Remember:
10 millimetres = 1 centimetre
1 metre = 100 centimetres = 1000 millimetres
1 kilometre = 1000 metres = 10,00,000 millimetres
1 gram = 1000 milligram
1 litre = 1000 millilitres.

Solved Examples:
Ex 1.

Insert commas suitably and write the names according to Indian System of Numeration :
(a) 87595762
(b) 8546283
(c) 99900046
(d) 98432701
Sol:
(a) 8,75,95,762 = Eight crore seventy-five lakh ninety-five thousand seven hundred sixty two.
(b) 85,46,283 = Eighty-five lakh forty-six thousand two hundred eighty-three.
(c) 9,99,00,046 = Nine croe ninety-nine lakh forty six.
(d) 9,84,32,701 = Nine crore eighty-four lakh, thirty-two thousand seven hundred one.

Ex 2.
Insert commas suitably and write the names according to International System of Numeration :
(a) 78921092
(b) 7452283
(c) 99985102
(d) 48049831
Sol.
(a) 78,921,092 = Seventy-eight million, nine hundred twenty-one thousand, ninety-two.
(b) 7,452,283 = Seven million four hundred fifty-two thousand two hundred eighty-three.
(c) 99,985,102 = Ninety-nine million nine hundred eighty-five thousand, one hundred two.
(d) 48,049,831 = Forty-eight million forty-nine thousand eight hundred thirty one.

Ex 3.
Population of Kota was 5,48,985 in the year 1995. In the year 1996 it was found to be increased by 1221. What was the population of the city in 1996?
Sol.
Population of the city in 1996
= Population of the city in 1995 + Increase in population
= 5,48,985 + 1221
Knowing Our Numbers Class 6 Maths 3

Types of Numbers:

(i) Natural Numbers: (N)
Set of all counting numbers from 1 to+∞,N = {1,2,3,4,… ∞}.
(ii) Whole Numbers: (W)
Set of all natural numbers including zero, W = {0,1,2,3,4,… }
(iii) Integers:
Set of all positive and negative of natural numbers including zero from – ∞, to + ∞, I or Z = {…,-3, -2, -1, 0, 1, 2, 3,
…}.
Positive integers {1, 2, 3, 4 }
Negative integers { -3, -2, -1}
(iv) Rational Numbers:
These are real numbers which can be expressed in the form of p/q, where p and q are integers and q ≠ 0. e.g., 2/3, 37/15,  /17/19 etc.
All the integers are rational numbers, because every integer can be expressed in the form p/q. For example, the integers
Knowing Our Numbers Class 6 Maths 5

Note:
1. All the fractions are rational numbers.
2. Every natural number is a rational number.
3. Every whole number is a rational number.
4. Every integer is a rational number.
5. Every fraction is a rational number.

Density property of rational numbers:
Between any two different rational numbers, there are infinitely many rational numbers. To find many rational numbers between two given distinct rational numbers, use the following method.
Knowing Our Numbers Class 6 Maths 4
Here q1, q2, q3, q4……….. are the rational numbers between two distinct rational numbers a and b.

Ex 1.
Find three rational numbers between 1/5 and 1/3.
Sol.
Let q1, q2, q3 be the three required rational numbers. Then
Knowing Our Numbers Class 6 Maths 6

Comparison of two rational numbers:
Using the arithmetical process:

  • Express each rational number with a positive denominator
  • Find LCM of the positive denominators
  • Express each of the given rational numbers with LCM as the common denominator
  • The number having greater numerator is greater

To compare two rational numbers p/q and r/s. we compare the products s × p and q × r and define their inequality as under

Knowing Our Numbers Class 6 Maths 7

Properties of rational number:
Decimal representation of a rational number:
We can represent a rational number as a decimal number by the long division process. We have three types of decimals. They are

  • Terminating decimals
  • Non-terminating and repeating decimals
  • Non-terminating and non-repeating decimals
  • Defination of terminating, non-terminating, recurring & non-recurring.

Ex.2:
√2, √3 etc.
Converting a decimal number into an equivalent rational number in the form of a/b
We can divide this into two parts :
Case – 1: When the decimal number is a terminating number. Express 0.3 as a rational number.
Sol.
0.3 = 3/10
Knowing Our Numbers Class 6 Maths 8

Introduction of irrational numbers:
Every rational number can be expressed either in terminating decimal form or non-terminating repeating (or periodic) decimal form. Consider the decimal number 0.1010010010001 We can see that no group of digits is repeating in a cyclic manner. So we have numbers whose decimal representation is neither terminating nor repeating. There are a number of such decimals. Such numbers are called irrational numbers.

Note:
A number is an irrational number, if it has a non-terminating and non-cyclic repeating decimal representation.

Real Numbers:
The set of rational numbers together with the set of irrational numbers are called ‘Real Numbers’, denoted by “R”

Whole Numbers:
The natural numbers along with zero form the collection of whole numbers. 0, 1, 2, 3, 4, 5, are whole numbers.

Successor:
Success of every number comes just after the number. Therefore, the successor of every number is obtained by adding 1 to the number.
For example: successor of 98 = 98 + 1 = 99

Predecessor:
Predecessor of every number comes just before the number.
For example: predecessor of 98 = 98 – 1 = 97

Representation of Numbers on Number Line:
Every number on number line represents position from its greater and smaller numbers. Negative, positive, whole, natural, prime, etc. All are represented on number line.
Numbers on number line are represented by the following:
Step 1:
Draw a line and mark a point zero on it.
Step 2:
Distance between the numbers is always equal. Therefore, the length of number line should be divided into required into required number of interval.
Step 3:
The arrow mark at the far end point of number line, indicates infinitive.

Ex:
Representation of whole numbers from 0 to 10 on number line.
Step 1:
Draw a horizontal line and mark a point 0 on it.
Step 2:
Mark another point and divide the distance among them into 10 equal parts.
Step 3:
Write numbers 1 to 10 at each division.
Knowing Our Numbers Class 6 Maths 9
Properties of whole numbers:
1. Addition:
Sum of any two whole numbers is always a whole number i.e. the collection of whole numbers is closed under addition.
For example : 2 + 3 = 5

2. Substraction:
Substraction of any two whole number is not always a whole number.
For example : 3 – 2 = 1 (whole number). But 2 – 3 = -1 (not whole number)

3. Multiplication:
Multiplication of any two whole number is always a whole number.
For example : 2 × 3 = 6, 2 × 0 = 0.

4. Division:
Division of any two whole number is not always a whole number.
For example : 6/3 = 2 (is whole number) 2/3 = (not a whole number)
3/0 (not possible)

Solved Examples:

Problem 1.
Add the following:
347 + 578 + 153
Sol.
We can group the numbers in different ways.
As 347 + 153 = 500,
So, we can group
347 + 578 + 153 = (347 + 153) + 578 = 500 + 578 = 1078

Problem 2.
Show that:
(63 + 49) + 37 = 63 + (49 + 37)
Sol.
(63 + 49) + 37 = 112 + 37 = 149
63 + (49 + 37) = 63 + 86 = 149
(63 + 49) + 37 = 63 + (49 + 37)

Problem 3.
Solve by suitable rearrangement.
32 × 25
Sol.
32 is equal to 8 × 4
So, 32 × 25 = 8 × 4 × 25
= 8 × (4 × 25)
= 8 × 100 = 800

Problem 4.
Simplify using properties .
4 × 16 × 125
Sol.
4 × 125 = 500
So, 4 × 16 × 125 = 16 × 4 × 125 = 16 × (4 × 125)
= 16 × 500 = 8000

Problem 5.
A florist arranges 6 gladioli and 7 roses in a bouquet. Raj buys 5 such bouquets for the school annual function. What is the total number of flowers in these 5 bouquets?
Sol.
Gladioli in 5 bouquets = 5 × 6 flowers = 30 flowers Rose in 5 bouquets = 5 × 7 flowers = 35 flowers Total number of flowers in 5 bouquets = (5 × 6) + (5 × 7) = 65 flowers Another ways of solving the problem is as follows.
Flowers in one bouquets (gladioli = roses) = (6 + 7) flowers
Total number of flowers in 5 bouquets = 5 (6 + 7) flowers = 5 × 13 flowers = 65 flowers
So, 5(6 + 7) = (5 × 6) + (5 × 7)
5 × 13 = 30 + 35
65 = 65
Hence, we can conclude that if a, b and c are whole numbers,
then a × (b + c) = a × b + a × c
This property is called the distributive property of multiplication over addition.

Problem 6.
7 × (8 + 3) = 7 × 8 + 7 × 3
Sol.
We can see that multiplication is distributed between 8 and 3 when the sign is one of addition.
Let us look at another example.
Knowing Our Numbers Class 6 Maths 10
6 rows of 5 squres + 6 rows of 4 squares
= 5 x 6 + 4 × 6 = 30 + 24 = 54 squares.
This is also equal to 6 rows of 9 squares.
6 × 9 = 54
So, 5 × 6 + 4 × 6 = 6 (5 + 4)
30 + 24 = 6 × 9
54 = 54

Problem 7.
There are 7 plates. Six biscuits are placed on each plate. If 4 biscuits are taken away from each plate, how many biscuits are left on the plates ? Write the mathematical statement.
Sol.
Biscuits on 7 plates = 7 × 6 = 42 biscuits
Biscuits taken away from 7 plates = 7 × 4 = 28 biscuits
Biscuits remaining = 7 × 6 – 7 × 4
= 42 – 28 = 14 biscuits
or, Biscuits left on one plate = (6 – 4) biscuits
Biscuits left on 7 plates = 7(6 – 4) biscuits
= 7 × 2 biscuits = 14 biscuits
So, the mathematical statement
7 × (6 – 4) = 7 × 6 – 7 × 4

Problem 8.
Write the place values of the bold digits in each of the following :
(a) 370345
(b) 2479034
(c) 42371509
