At the Hardey Fitness Center, the management did a survey of their membership. The average age of the female members was 40 years old. The average age of the male members was 25 years old. The average age of the entire membership was 30 years old. What is the ratio of the female to male members? Express your answer as a common fraction.

 

Thanks!

Let f be the number of female members and m be the number of male members. We know the following:

40f + 25m = 30(f + m)

Simplifying this equation, we get:

15f = 5m

Therefore, the ratio of female to male members is f/m=1/3.

Hmm!  Check the left-hand side of 15f = 5m

Thanks for your answer, but as Alan has informed us, I think the simplified equation should be 10f=5m.

Otherwise, thanks a lot!!
