Sagot :

This is going to be part over whole, so the part is the science and adventure movies put together (because that is all movies except comedy) so we have 12 as our numerator.
Our whole is all movies which adds up to 20 and that will be our denominator. So, 12/20 can be simplified to 3/5 or 0.6 or 60% (those are the answers)
