Daily Life Problems (World Problems) about Fraction Part 2

Actually, I have posted some daily life problems about fraction in the previous post. But, in here I want to post about it again. If for the 1st part, I consent about the using of addition and subtraction, so for the second part, I consent on the multiplication and division more. The file that I upload is the handout that I use in the class, if it can help you in studying mathematics, you can download the handout in here.

If you have any question, please ask.

Flat Figure

This is the handout for chapter: Flat Figure. The flat figures that we will discuss is only triangle and quadrilaterals. If you miss the note in my class, then you can download it here. And if you have any question, please ask.

I hope the handouts can help you in studying mathematics.

Division of Fraction

This is the handout of presentation that I use in class for the topic "Division of Fraction". If you need it, you can download it here.

I hope the handout can help you in understanding the topic about division of fraction. If you have any question, please ask.

Multiplication of Fraction

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.
