Arithmetic Grade Five

Lesson One hundred and Thirty-three: Wholes and Percents

The following percent times whole problems are easy to figure out in your head. 


	30% * 90 = 27
	50% * 50 = 25
	40% * 80 = 32
	20% * 30 =  6
Sometimes they aren't quite so easy: 

    40 * 25% = 

	   40		
	x .25		
	------		
	  200		
	  80		
	------		
	10.00		

    200 * 75% = 

	  200
	x .75
	------
	 1000
	1400
	------
	150.00

Now you get to try a few for yourself.
