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

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

# 10% - We divide the amount by 10 because 10% is one tenth

# 50% - We divide the amount by 2 because it is a half

# 25% - We divide the amount by 4 because it is a quarter

# 75% - is three-quarters, so we can divide by 4 and multiply by 3

# 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

**Answer**

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

**Answer**

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**
