Lesson One Hundred and Nine: Mixed Number Multiplication I

Multiplying mixed numbers involves a preparatory step where you convert the mixed numbers into improper fractions. So, we will review this procedure before going further. 


	To convert 2 3/4 to an improper fraction multiply the
	whole number by the denominator and add this amount to
	the numerator. Write this amount over the denominator.

	2 * 4 + 3 = 11

	ANSWER 11/4
Here's another example: 

	IMPROPER FRACTION:		3 2/5

	CALCULATION: 			3 * 5 + 2 = 17

	MIXED NUMBER:			17/5
Here's yet another example: 

	IMPROPER FRACTION		4 1/2

	CALCULATION:			4 * 2 + 1 = 9

	MIXED NUMBER:			9/2
