Okay today in class we got our tests back and I'm sure that most of us were happy with our mark and some of us not so much. Today in class we were also talking about the problem with Carol Garden and Flat Bush, but I don't know if I have to do that one, so I'm not because my dad if about to unplug my internet, sorry.

Now for homework today we had nine questions for multiplying fractions I am going to do three different questions, so you can see how to do them. :]

My first question is one form the two that you had to draw a picture for.
The question is 4/5 x 1/2 or 1/2 of 4/5.
Now first I will solve it. So all I have to do is multiply the denominators and multiply the numerators.
(numerators) 4 x 1 = 4
(denominators) 5 x 2 = 10
4/5 x 1/2 = 4/10
Now simplify
4/10 = 2/5

PICTURE

I think that's how you make the picture, but I am not sure because well I just don't know how to draw a picture of multiply fractions.

The next question is 3/4 x 1/2 x 6/7=?
3 x 1 x 6 = 18
4 x 2 x 7 = 21
3/4 x 1/2 x 6/7 = 18/21
now simplify.
18/21 = 6/7
YAY!! I hope!

Okay next question is 9/10 x 5/18.
Now first I am going to switch around the 5 and the 9 because it doesn't matter which side it is on because you are multiplying them together anyways.
So now the question is 5/10 x 9/18 or 1/2 x 1/2, now that is much more friendly. :]

1 x 1 = 1
2 x 2 = 4
1/2 x 1/2 = 1/4

There I hope it helped. Sorry I didn't do all of them
