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
