Step by step
The question
Question: 32 is 8% of what number?
8% of ? = 32
We write it like this: 8% of the number is 32.
32 is a part.
The whole number is what we want.
? = the whole number
Careful!
Many people work out 8% of 32.
But 32 is not the whole.
It is only 8% of it.
Careful: not 8% of 32 ✗
1 Find 1%
8% is 8 lots of 1%.
So we find 1% first.
8% = 8 × 1%
1% is 32 divided by 8: 4.
1% of ? = 32 ÷ 8 = 4
2 Find 100%
The whole number is 100%: 100 lots of 1%.
100% = the whole
4 times 100 is 400.
100% of ? = 4 × 100 = 400
So 32 is 8% of 400.
3 Check
Let's check: is 8% of 400 really 32?
8% is 8/100.
Of means times.
8% of 400 = 8100 × 400
400 divided by 100 is 4.
8 times 4 is 32.
= 8 × 4 = 32 (400 ÷ 100 = 4)
We get 32.
So it is right!
Let's look back.
First: find 1%.
Then: find 100%.
Last: check.
Answer
100% of ? = 4 × 100 = 400
