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.
