There are 3 times as many females as males on the maths course at university. What fraction of the course are female? Give your answer in its simplest form

Answer 1

F=3M

M=F/3

F/(M+F) = the fraction of the course that are female

number of females divided by total number (M+F)

F/(M+F) = F/(F/3 + F) = F/(4/3)F = 1/(4/3) = 3/4

3 out of 4 students are female, that's 3/4

Or you could say 75% or 0.75
