Write 1/2 as a decimal

Step by step

The question

Question: write 1/2 as a decimal.

1 Make the bottom 10, 100 or 1000

A decimal is tenths, hundredths, thousandths.

So we want a bottom of 10, 100 or 1000.

2 times 5 is 10.

We multiply the top and the bottom by 5.

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

1 times 5 is 5.

So we get 5/10.

2 Write the decimal

10 has 1 zero.

So the decimal has 1 digit after the point.

5 tenths is 0.5.

3 Check

Let's check: the decimal times the bottom should give the top.

0.5 times 2.

Forget the points: 5 times 2 is 10.

The numbers have 1 digit after the point.

So the answer has 1 too: 1.0, which is 1.

We get 1, the top.

So the answer is right!

Let's look back.

First: make the bottom 10, 100 or 1000.

Then: write the decimal.

Last: check.
