To find 10% of a number we must find one tenth (1/10) of it.

One way to do this is to divide the number by 10.

To find 20% of a number we first find 10% and then double the result.

Example

Find 20% of 530

Answer

First, we find 10% which is 530 ÷ 10 = 53

Then we double the result to get 53 x 2 = 106

It's that simple!
