Write 12.5% as a decimal

Step by step

The question

Question: write 12.5% as a decimal.

1 Write it over 100

Percent means out of 100.

So 12.5% is 12.5/100.

A fraction is written with whole numbers.

So we multiply the top and the bottom by 10.

12.5 times 10 is 125.

100 times 10 is 1000.

2 Write the decimal

1000 has 3 zeros.

So the decimal has 3 digits after the point.

125 thousandths is 0.125.

The short way: the point moves 2 places to the left.

3 Check

Let's check: go back.

0.125 is 125 thousandths.

That is 12.5/100.

So it is 12.5%.

So the answer is right!

Let's look back.

First: write it over 100.

Then: write the decimal.

Last: check.
