at a small private collage, 9/20 of the students are female. there are 2160 female students, then how much are male?

since 9/20 were female, 11/20 were male

11/9 * 2160 = 2640 males.

20/20 - 9/20 = 11/20

Then, since the ratio between male and female is 11/20 / 9/20 = 11/20 * 20/9 = 11/9, we can use this to figure the amount of males. multiply by 2160 (number of females) to get 2640.
