How to convert 4.5 into a decimal
stiks02 [169]
When you ask, "What is 4.5 as a decimal?", we assume you want to know what 4.5 percent is as a decimal. In other words, 4.5 percent converted to decimal.

First, we will tell you why it is useful to know 4.5 as a decimal.

Normally, to calculate 4.5 percent, you would multiply a number by 4.5 percent and then you would take the product of that and divide it by 100 to get the answer.

Instead, you can simply multiply a number by 4.5 as a decimal to get the answer.

4.5 percent means 4.5 per hundred. Therefore, to get 4.5 as a decimal, all you have to do is divide 4.5 by 100 like so:

4.5 ÷ 100 = 0.045
