Step by step
The question
Question: work out 35% of 240.
35% of 240 = ?
Percent means out of 100.
So 10% is 10 out of 100: one tenth.
To find 10%, we divide by 10.
10% = ÷ 10
1 Find 10%
240 divided by 10 is 24.
10% of 240 = 240 ÷ 10 = 24
2 Build 35%
We build 35% from easy pieces: 35% is 30% and 5%.
35% = 30% + 5%
30% is 3 times 10%.
3 times 24 is 72.
30% of 240 = 3 × 24 = 72
5% is half of 10%.
Half of 24 is 12.
5% of 240 = 24 ÷ 2 = 12
3 Add the pieces
Now we add the pieces.
35% of 240 = 72 + 12
72 plus 12 is 84.
= 84
So 35% of 240 is 84.
Let's look back.
First: find 10%.
Then: build 35%.
Last: add the pieces.
Answer
= 84
