1. Convert each of the following into a Percentage:

(i) 6/15

(ii) 3/25

(iii) 0.25

(iv) 2 2/5

Solution:

(i) 6/15
The given fraction is 6/15,
to convert the given fraction into a percentage,
we will multiply the fraction by 100,
6/15 ×100,
on solving, we will get 40%.

(ii) 3/25

The given fraction is 3/25,
to convert the given fraction into a percentage,
we will multiply the fraction by 100,
3/25 ×100,
on solving, we will get 12%.

(iii) 0.25

The given decimal is 0.25,
to convert the given decimal into a percentage,
we will multiply the fraction by 100,
0.25 ×100,
on solving, we will get 25%.

(iv) 2 2/5

The given fraction is 2 2/5,
which is 12/5
to convert the given fraction into a percentage,
we will multiply the fraction by 100,
12/5 ×100,
on solving, we will get 240%.

2. Which of the following is equal to 45%?

a) 0.45
b) 0.0045
c) 9/25
d) 0.045

Solution:

The given percent is 45%,
now we will divide the given value with 100
= 45/100
on solving, we will get the result in decimals
= 0.45.
So the option a is the correct option.

3. Solve out the number when increased by:

(i) 3.2% becomes 360

(ii) 30% becomes 7,800

(iii) 25% becomes 1,800

Solution:

(i) 3.2% becomes 360
Here, we should find out the number,
So the number be X
as given 3.2% was increased,
So, increased number= X +(3.2% × X), on solving we will get
= 1.032X
given that the number which when increased by 2.6% becomes 360, which means
1.032X =360, on solving we will get
X = 348.83.

(ii) 30% becomes 7800

Here, we should find out the number,
So the number be X
as given 30% was increased,
So, increased number= X +(30% × X), on solving we will get
= 1.3X
given that the number which when increased by 1.3% becomes 7,800, which means
1.3X =7800, on solving we will get
X = 6,000.

(iii) 25% becomes 1800

Here, we should find out the number,
So the number be X
as given 25% was increased,
So, increased number= X +(25% × X), on solving we will get
= 1.25X
given that the number which when increased by 25% becomes 1800, which means
1.25X =1800, on solving we will get
X = 1,440.

4. Solve the following:

(i) 90 cm as a percent of 3 m.

(ii) 40 mins as a percent of 3 hours.

(iii) 2.25 mm as a percent of 0.5 cm.

Solution:

(i) 90 cm as a percent of 3 m.
Given 90 cm of 3m,
as 1m= 100 cm, so first we will convert meters to centimeters
3m= 300 cm,
90/300 × 100 =
on solving we will get the result as
= 3%.

(ii) 40 mins as a percent of 3 hours.

Given 40 mins of 3 hours,
as 1 hour = 60 minutes, so we will convert hour to minutes,
3 hours= 180 minutes,
40/180 × 100=
on solving we will get the result as
22.22%.

(iii) 2.25 mm as a percent of 0.5 cm.

Given 2.25mm of 0.5 cm
as 1 cm= 10 mm, so we will convert cm to mm
0.5 cm = 5 mm,
2.25/5 × 100=
on solving we will get
45%.

5. Express each of the following rational numbers percentages into a ratio in the simplest form:

(i) 8/7 %

(ii) 25/6 %

Solution:

(i) 8/18 %
To convert a rational number Percentage into a Ratio, we will divide the percentage by 100 and will reduce the given fraction into the simplest form, and then we will write the number with a ratio sign
= 8/7 × 1/100
on simplifying we will get
= 2 : 175.

(ii) 25/6 %

To convert a rational number Percentage into a Ratio, we will divide the percentage by 100 and will reduce the given fraction into the simplest form, and then we will write the number with a ratio sign
= 25/6 × 1/100
on simplifying we will get
= 1 : 24.

6. what will be the percent of each angle if the angles of a triangle are 4:2:4?

Solution:

The given angles are 4:2:4, so 4+2+4= 10 parts.
To convert the given ratio to percent we will multiply by 100
The percentage for the first angle is 4/10 × 100= 40%
The percentage for the second angle is 2/10 × 100= 20%
The percentage for the third angle is 4/10 × 100= 40%.
