To get x percent of a number n you multiply x and n and divide the answer by 100,

But to get 15% there is a short cut:

Step 1: Divide the number by 10 - that gives you 10%. Easy if you can work decimal points.

Step 2: Halve the answer - that gives you 5%

Step 3: Add together the results of steps 1 and 2.
