The ratio of male to female players in Belfort Tennis Club is 3:5. The club has a total of 240 players.
In the mixed doubles one male player partners one female player.
How many female players will not have a male partner?

please help, I am struggling with learning at home and would appreciate it very much if you could assist me

First of all, to find the ratio of male to female players you need to add the 5 and the 3 to get 8
You then need to divide 240 by 8 to get 30
You then multiply 30 by 3 to get 90 and 30 by 5 to get 150 respectively
The number of male players is 90 and female players is 150
You then do 150-90 which is 60
There is 60 females without male partners

The answer is part a: use
