The question

Question: write 0.5 as a fraction.

0.5

1 Read the place value

0.5 has 1 digit after the point.

The last digit is in the tenths.

So we write it over 10.

1 digit after the point → over 10

0.5 is 5 tenths: 5/10.

= 510

2 Simplify

5 and 10 can both be divided by 5.

That makes it simpler.

= 5 ÷ 510 ÷ 5

So it is 1/2.

= 12

Can we make it simpler?

No number goes into both 1 and 2, except 1.

So it stays like this.

3 Check

Let's check: make the bottom 10 again.

1 times 5 is 5.

2 times 5 is 10.

5 tenths is 0.5.

So the answer is right!

Check: 12 = 1 × 52 × 5 = 510 = 0.5

Let's look back.

First: read the place value.

Then: simplify.

Last: check.
