Total actors = 28
8 actors are men so the number of women who are actresses will be
Total actors - male actors
Female actors = 28 - 8 = 20
The ratio of men to women = 8 : 20
To simplify, decrease ratio to its simplest form. The lowest common factor of both numbers is 2. Divide both sides by 2 until it can be divided no more
8 : 20 = 4 : 10 = 2 : 5
The ratio of men to women in simplified rational form is 2 : 5
