Worksheet Overview

This activity is about finding percentages of numbers.


It is easy to find 10% of any number because 10% = 10/100 = 1/10


Simply divide by 10:

So 10% of 192 is 19.2 

10% of 54 g is 5.4 g etc.


When you know 10%, it is easy to find 1% - simply divide by 10 again!


To find 2%, we can find 1% and multiply by 2.

To find 5%, we can find 10% and divide by 2.

To find 30%, we can find 10% and multiply by 3.


We can then add any combinations together!



Find 65% of 340.


10% is 34

So, 60% is 6 × 34 = 204

5% is 34 ÷ 2 = 17


65% = 204 + 17 = 221


You can work out percentages on a calculator either by using the % key, or by multiplying the number by the required percentage and dividing by 100.




For this activity, we will be using the method above, so no calculators allowed!!


Let's get started on the questions.
