Write 45% as a fraction

Step by step

The question

Question: write 45% as a fraction.

1 Write it over 100

Percent means out of 100.

So 45% is 45/100.

2 Simplify

45 and 100 can both be divided by 5.

That makes it simpler.

So 45% is 9/20.

Can we make it simpler?

No number goes into both 9 and 20, except 1.

So it stays like this.

3 Check

Let's check: make the bottom 100 again.

20 times 5 is 100.

9 times 5 is 45.

45 out of 100 is 45%.

So the answer is right!

Let's look back.

First: write it over 100.

Then: simplify.

Last: check.
