Arithmetic Grade Five

Lesson Fifty-four: Decimal Multiplication

You can multiply more than one number in a single problem. Consider this example: 

	.4 x .8 x .3 = .32 x .3 = .096
We started out with three numbers in a single multiplication problem. Then we multiplied the first two (.4 x .8 = .32). This gave us .32 x .3 which equals .096. We could have arrived at the same answer by completing this problem in a different order. 

	.4 x .8 x .3 = .4 x .24 = .096
Or we could even rearrange the problem and do it like this: 
 
	.4 x .3 x .8 = .12 x .8 = .096
