To Find the Percent of a Given Number

What is 18% of 500? 18% of 500 represent 18 parts out of hundred, so 18% of 500 represents 18 parts for each hundred which is 18 + 18 + 18 + 18 + 18 = 90. Thus, 18% of 500 = 90

So, 18% of 500 = 18100 × 500 = 18 × 5 = 90

To find the percent of a given number let us consider some of the following examples.

1. Find 50% of 75.

Solution:

50% of 75

= 50 × 1/100 × 75

= 50/100 × 75

= (50 × 75)/100

= 3750/100

= 3750/100 ÷ 50/50

[Divide the numerator and denominator by 50]

= 75/2

3. Find 12% of 250.

Solution:

12% of 250

= 12 × 1/100 × 250

= 12/100 × 250

= (12 × 250)/100

= 3000/100

= 3000/100 ÷ 100/100

[Divide the numerator and denominator by 100]

= 30

Answer: 30

4. Find 30% of 86.

Solution:

30% of 86

= (30 × 86)/100

= 2580/100

= 2580/100 ÷ 20/20
