Yes you do multiply the same denominator. 1/2 * 1/2 = 1/2*2 = 1/4
In multiplication of fractions, you multiply everything: the numerator * numerator, and denominator * denominator, no matter what the number values are.

ya
so 5/2 * 8/7
= (5*8) / (2*7)
=40/14
or 20/7

5 / 12 * 7 /9 = ( 5*7) / ( 12*9)

No the denominator does not have to be the same, unlike when adding fractions.
