Multiply the numerators and denominators. Simplify if needed.
Ex. 4/5 x 5/10 = 20/50 or 2/5
Cross Cancellation:
If there's a number in the numerator and denominator that are both divisible by a number, divide it with that number and multiply
Ex.
4 10
-- x -- = N
5 16
*Change 4 to 1 and change 16 to 4.
*Change 10 to 2 and change 5 to 1.
Turns out like this:
1 2 2 1
-- x -- = -- or --
1 4 4 2
