What percent of 20 is 5

Step by step

The question

Question: what percent of 20 is 5?

Percent means out of 100.

So we ask: 5 out of 20 is how many out of 100?

1 Write part over whole

5 is the part.

20 is the whole.

We write part over whole.

2 Make the bottom 100

Percent means out of 100.

20 times 5 is 100.

So we multiply the top and the bottom by 5.

5/5 is 1.

Times 1 does not change the size.

5 times 5 is 25.

20 times 5 is 100.

25 out of 100 is 25%.

So 5 is 25% of 20.

3 Check

Let's check: is 25% of 20 really 5?

25% is 25/100.

Of means times.

To keep the numbers small, we divide the top and the bottom by 25.

That is 1/4.

20 divided by 4 is 5.

That is 5.

We get 5.

So it is right!

Let's look back.

First: write part over whole.

Then: make the bottom 100.

Last: check.
