Percentages

How to find a percentage of something.

There are three easy ways.

1. Multiply by the percentage and divide by 100.

eg. 67% of 250 = 67 x 250 ÷ 100 = 167.5


2. Turn the percentage into a decimal and multiply.

eg. 67% of 250 = 0.67 x 250 = 167.5


3. Convert percentage into fraction and find the fraction

25% of something is a quarter of something (ie. divide by 4)

Other percentages - fractions:
20% is 1/5
10% is 1/10
5% is 1/20

(The first two methods will always work and are very easy to do if you have a calculator. The third method is good if you want to do something quickly without a calculator and it is a percentage that easily turns into a fraction)


If you're feeling confident with the third method, you could try and combine different fractions to make percentages.

eg. 75% = 50% + 25% = 1/2 + 1/4 !
