In this worksheet, students will find percentages of numbers, quantities and measurements. Key stage:  KS 3

Curriculum topic:   Number

Curriculum subtopic:   Define, Interpret and Compare Percentages

Difficulty level:   #### Worksheet Overview

This activity is about finding percentages of numbers, quantities, and measurements.

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!

Example

Find 43% of 212 m

10% of 212 m is 21.2 m

40% of 212 m is 21.2 × 4 = 84.8 m

1% of 212 m is 21.2 ÷ 10 = 2.12 m

3% of 212 m is 2.12 × 3 = 6.36 m

43% of 212 m = 40% + 3% = 84.8 + 6.36 = 91.16 m

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 calculators allowed only for complicated divisions or multiplications!
