To convert percent into a decimal, divide it by 100. This can be accomplished by moving the decimal point 2 places to the left:

`220.0%-> 2.2` 

To find 220% of 18, use the formula `A = pB` , where A is the amount (unknown), p is the percent rate expressed as a decimal (2.2) and B is the base (number the percent is calculated of, 18.)

`A = 2.2*18 = 39.6`

The answer is 39.6.

Thank you! Could you try 5% of 12 as a decimal?

First we convert 5% into a decimal by dividing 100 = 5/100 = 0.05

then amount of 5% of 12 = 0.05 x 12 = 0.6

The answer is 0.6.

A piece of advice i would give would be to divide the percentages by 100 and then multiply that number but the number whose percentage you are trying to find:

220% of 18

220/100 = 2.2

2.2 x 18 = 39.6

Whenever you have percents, you just put that number over 100. You get a fraction. Then you multiply the numerator times 85. Then divide the answer by 100. For example if you have 10% of 85, you do:

`10/100 * 85=`

`850/100=`

`8.5`

10% of 85 is 8.5. The same way, you can solve for 220% of 18. You can also instead divide 220 divided by 100, then multiply the answer by 18.

`220/100 * 18=`

``2.2 times 18=

39.6. If you either divide the fraction then multiply. Or multiply numerator times the number then divide by 100, you get the same answer. So the answer is 39.6
