I couldn't upload my video, so here is the link for now.

The next thing we had to do is show how to multiply a fraction by a fraction, a fraction by a mixed number and a mixed number by a mixed number.

Fraction x Fraction

1/2 x 1/2

1)you multiply the numarator by numarator to get the first answer.

1x1=1

2)you multiply the denominator by denominator to get the second answer.

2x2=4

so the answer is 2/4 (always simplfy)2/4=1/2.

Fraction x Mixed Number

3 x 1/2=

1)the whole number (3 ) is the number of groups.

2)the fraction (1/2) is how many in each group.

3 x 1/2=3/2(simplfy)1 1/2

Mixed Fraction x Mixed Fraction

When converting you use the denominator to decide the number of parts in 1 whole.

2 1/2 x 1 3/4=?

2/2 + 2/2 + 1/2=5/2

4/4 + 3/4=7/4

7/4 x 5/2= 35/8(simplfy) 35 divided by 8 = 4.375

4 x 8 = 32

35-32=3

so the answer is 4 3/8
