How do you multiply fractions with cross canceling

1 answer:

5 0

3 9
_ * _
15 6

Compare diagonally to see if they the 2 numbers simplify.

Ex:

3 and 6 Simplify to 1 and 2 because they are both multiples of 3.

9 and 15 Simplify to 3 and 5 because they are both multiples of 3 as well.

Now our fractions are

1 3
_ * _
5 2

Now multiply across to get your final fraction/answer

3
_
10
