#### Worksheet Overview

In this activity, we will find percentages of given amounts!

Recap of common percentages (Make a note of these!)

# 1%  - We divide the amount by 100 because 1% is one hundredth

We can use these simple percentages to find other percentages!

Let's have a look at some!

Example 1

Find 20% of 340

We know how to find 10%  - we divide by 10.

20% is made up of 2 x 10% (2 lots of 10%)

We can find 10% then multiply by 2.

10% = 340 ÷ 10 = 34

20% = 34 x 2 = 68

Example 2

Find 15% of 360

We know how to find 10%  - we divide by 10

5% is half of 10% (Divide 10% by 2)

We can find 15% by adding 10% and 5% amounts together.

10% = 360 ÷ 10 = 36

5%  = 10% ÷ 2 = 36 ÷ 2 = 18

15%  = 10% + 5% = 36 + 18 = 54

Let's try some questions!
