3/5 of the female members and 1/3 of the male members attended a meeting. 108 members attended the meeting. There were 260 members in the club. How many more male than female members were there in the club?

3/5 m + 1/3 f = 108
m + f = 260
clear fractions to get
9m + 5f = 1620
m + f = 260
9m + 5f = 1620
5m + 5f = 1300
4m = 320
m = 80
f = 180
3m/5 = 48
f/3 = 60
48+60=108
