if there is 16 females and the ratio is 3:4 it would be 12 due to 4 times 4 being 16. Meaning that i would do 3 times 4 which would result in having 12 male teachers.
If the ratio is 3:4, and the number of female teachers is 16, then the number of male teachers must be 12. This can be confirmed by multiplying both 3 and 4 by 4, or 12/16 = 3/4.
