Write 7/20 as a percent

Step by step

The question

Question: write 7/20 as a percent.

1 Make the bottom 100

Percent means out of 100.

So we want a bottom of 100.

20 times 5 is 100.

We multiply the top and the bottom by 5.

5/5 is 1, so the value stays the same.

7 times 5 is 35.

So we get 35/100.

Careful!

As a decimal, 7/20 is 0.35.

But 0.35% means 0.35 out of 100: far too small.

2 Write the percent

35 out of 100 is 35%.

3 Check

Let's check: go back.

35% is 35/100.

Divide the top and the bottom by 5.

We get 7/20.

So the answer is right!

Let's look back.

First: make the bottom 100.

Then: write the percent.

Last: check.
