Arithmetic Grade Six

Lesson One Hundred-Thirteen: Improper Fractions

In this lesson we will be dealing with a lot of improper fractions. Take this problem for instance: 


	 11	 7	
	---  *  ---  =
	 2	 6

	Since we can't reduce in any way, we just multiply the 
	numerators and denominators and get 77/12. (In this lesson
	we won't bother converting to mixed numbers.)
Here's another example: 

	 5	 8	
 	---  *  --- =
	 4	 3

	We can cross-reduce the 8 and the 4 which will
	change the problem to this:

	 5	 2
	---  *  --- =
	 1	 3

	Now we just multiply and we get 10/3.

Now you get to try a few for yourself.
