(2-1) Multiply Fractions.

To multiply fractions, multiply the numerators and then the

denominators. Notice that the denominators do not have to be the same.

3 1 3 1 3
4 2 4 2 8 3
4
Note that:

There are 3 parts of 4 colored blue, and
1 part of 2 colored yellow.

So there are 3 parts of 8 colored twice 2

(colored green).
To multiply mixed numbers both factors

must be in the form of fractions.

1 2 1 4 3= 7
