1. Are 4/8 and 6/12 Equivalent Rational Numbers?

Solution:

If Two Numbers are Equivalent Rational Numbers then the product obtained by cross multiplying them would be equal

4*12 = 48

8*6 = 48

Therefore, 4/8 and 6/12 are Equivalent Rational Numbers.

2. Express Rational Number 8/5 with a Numerator 56?

Solution:

In Order to Express Rational Number 8/5 with a Numerator 56

Numerator = 56

To make the rational number 8/5 with a numerator 56 firstly we need to divide the 56 by 8 i.e. 7

Multiply with 7 both the numerator and denominator of rational number 8/5

= 8/5*7/7

= 56/35

Thus, Rational Number 8/5 can be expressed as 56/35 with a numerator 56.

3. Are 3/7 and 4/5 Equivalent Rational Numbers?

Solution:

If Two Numbers are Equivalent Rational Numbers then the product obtained by cross multiplying them would be equal.

3*5 = 15

7*4 = 28

Thus 15 ≠ 28

Therefore, 3/7 and 4/5 are Not Equivalent Rational Numbers.

4. Express Rational Number 3/7 with a Denominator 49?

Solution:

To write the rational number 3/7 with a denominator 49

we need to find the number that when multiplied results in denominator 49

49/7 = 7

Multiply with 7 both the numerator and denominator of the rational number 3/7

= 3/7*7/7

= 3*7/7*7

= 21/49

5. If p/q = m/n then which of the following is true is always true?

a)n/m = p/q b)p*q=m*n c)p/n = m/q d)p*n = m*q

Solution:

d)p*n=m*q

If Two Numbers are Equivalent Rational Numbers then the product obtained by cross multiplying them would be equal.

6. A Rational Number Equivalent to 2/1 is

a)10/-5 b)10/5 c)-10/5 d) None of the above

Solution:

b) 10/5

2/1 = 2*5/1*5

= 10/5

Therefore Rational Number Equivalent to 2/1 is 10/5

7. What is the Rational Number Equivalent to 5/8

a)25/40 b) 25/-40 c)-25/40 d)None of the above

Solution:

a) 25/40

5/8 = 5*5/8*5

= 25/40

Rational Number Equivalent to 5/8 is 25/40

8. Fill in the blank to make Two Rational Numbers Equivalent

a) 4/7 = …./56

Solution:

32

In order to make the Rational Number 4/7 with denominator 56 we have

4/7 *8/8 = 32/56

Therefore, 4/7 is Equivalent to the Rational Number 32/56.

9. If 1/x = -x/1 then x is ……..

a) Whole Number b) Natural Number c) Rational Number d) Not a Rational Number

Solution:

d) Not a Rational Number

1/x= -x/1

-x2 = 1
x2 = -1
x= √ -1

Therefore, x is not a Rational Number.

10. Select the rational numbers which can be written as a rational number with denominator 4 from the following

7/3, 64/11, 30/(-12), (-16)/17, 5/(-4), 140/28

Solution:

30/(-12), 5/(-4), 140/28

Since all the above options can be rearranged to get a Rational Number with the Denominator 4.
