Write 1.25 as a fraction

Step by step

The question

Question: write 1.25 as a fraction.

1 Read the place value

1.25 has 2 digits after the point.

The last digit is in the hundredths.

So we write it over 100.

1.25 is 125 hundredths: 125/100.

2 Simplify

125 and 100 can both be divided by 25.

That makes it simpler.

So it is 5/4.

Can we make it simpler?

No number goes into both 5 and 4, except 1.

So it stays like this.

3 Write as a mixed number

5 divided by 4 is 1, with 1 left over.

So it is 1 and 1/4.

4 Check

Let's check: make the bottom 100 again.

5 times 25 is 125.

4 times 25 is 100.

125 hundredths is 1.25.

So the answer is right!

Let's look back.

First: read the place value.

Then: simplify.

Then: write as a mixed number.

Last: check.
