In a class, 50% of the male students and 2/3 of the female students speak French. If there are 3/4 as many girls' as boys, What fraction of the entire class speaks French?

Let themale student be 100. Then french speaking males are 50.

Therefore the girls students would be (3/4)*100 = 75 and French speaking girls student would be 75 * (2/3) = 50

Now, Total students = 175

Total french spoken student = 100

so fraction of entire class who speaks french is 100/175 = 4/7
