Question

To multiply fractions, first find a common denominator

Answer 1

Greetings! 

When multiply/dividing fractions, you DON'T find a common denominator. You only need to find a common denominator of two fractions when adding or subtracting.

Multiplying/Dividing Fractions:
3/4*5/8
3*5=15
4*8=36
15/36

Adding/Subtracting Fractions:
1/2+3/10
Find Common Denominator.
5/10+3/10
=8/10
Reduce.
=4/5

Hope this helps.
