Lesson One Hundred-Fourteen: Mixed Multiplication II

Mixed multiplication involves plenty of steps including two conversions, possible reducing, and multiplication. So, it's understandable that you might need a lot of practice to really master the entire process.

So, here's another example for you to study: 


	ORIGINAL PROBLEM: 			1 1/10 * 2 2/3 =

	CONVERT TO IMPROPER FRACTIONS:		11/10 * 8/3 =

	REDUCE (if possible):			11/5 * 4/3 =

	MULTIPLY:				44/15

	CONVERT ANSWER TO MIXED:		2 14/15
If you can master all these steps, then you won't have any trouble with mutliplying mixed numbers. Here's yet another example: 

	ORIGINAL PROBLEM: 			2 1/3 * 1 4/5 =

	CONVERT TO IMPROPER FRACTIONS:		7/3 * 9/5 =

	REDUCE (if possible):			7/1 * 3/5 =

	MULTIPLY:				21/5

	CONVERT ANSWER TO MIXED:		4 1/5

Now you get to try a few.
