In multiplying fractions, you multiply the numerators and denominators.
51 / 2 * 21 / 3
can be reduced as
(17 / 2) * (21 / 1)
357 / 2 --> This is the answer based on the given.
Assume that its a mixed fraction:
5 1/2 * 2 1/3
11/2 * 7/3
= 77 /6
Sometimes people would say 22. So try 22.

It says 20% OFF, so you would do, 1 - 0.20 = 0.80, so you would multiply 0.80 with 80 and get 64.
