Lesson One hundred and Thirty-three: Wholes and Percents

Percents are just like decimals when it comes to multiplication: 


	.7 * 70 = 49
	70% * 70 = 49
You just have to remember that 70% equals .7 and so the following steps will help you to multiply percents and wholes: 

	1. Convert the percent into a decimal
	2. Multiply the decimal and the whole
Here are some examples: 

	50% * 20 = 

	1) convert 50% to .5
	2) multiply .5 * 20 
	ANSWER: 10

  ------------

	20% * 100 = 

	1) convert 20% to .2
	2) multiply .2 * 100
	ANSWER: 20

  ------------
	
	35% * 200 =

	1) convert 35% to .35
	2) multiply .35 * 200
	ANSWER: 70

Now you get to try a few for yourself.
