Question

How to convert percentage to decimals.

Answer 1

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.

If we want to convert any percent to a decimal, you want to think of the percent as a ratio of the percent to 100 or the percent divided by 100.

Dividing by 100 moves the decimal point 2 places to the left so we will move the decimal point 2 places to the right to get our answer.

Let's look at an example.

Write the following percent as a decimal. 9%

We know that we can change a percent to a decimal by simply moving the decimal point 2 places to the left.

So in this problem, to write 9% as a decimal, we simply move the decimal point 2 places to the left and fill in the missing position with a zero.

So 9% can be written as the decimal .09 or 0.09.

A common mistake in this problem is to write 9% as the decimal 0.9 but remember to move the decimal point 2 places to the left so our answer is 0.09.
