How do I multiply fractions with different denominators? Do I always do cross multiplication?
EX: Xy, when X = 5/16 and y = 7/15.
2. How do I write 12/5 as a whole number?

Math 
PsyDAG,
(5/16)(7/15) = 35/240 = 7/48
It will not be a whole number, but mixed = 2 2/5 = 2.4
I hope this helps. Thanks for asking.
