Actually, we have already discuss the topic about multiplication and division in fraction. So, after mid semester test, we will doing kinds of review about it. But, if you still face some difficulties, then we will concentrate on it more.
This is the handout of power point presentation that I use in the class. If you need it, you can download it here.

Be careful! Some of you doing the same mistake in multiplication involves percent.
For example:
20% x 40%
REMEMBER that
20% = 20/100, and
40% = 40/100
So, 20% x 40% = 20/100 x 40/100
= (20 x 40)/(100 x 100)
= 800/10.000
= 8/100 = 8%
Some of you do it like this,
20% x 40% = (20 x 40)%
= 800%
That's completely WRONG!!!
So be careful with multiplication involves percent. If you have any question, please ask.
