Two thirds of men in charlotte are marriedc to three forths the women, how many people are married?

can you please show how to do this problem!Two thirds of men in charlotte are marriedc to three forths the women, how many people are married?
(2/3)Men = (3/4)Women





Men/Women = (3/4)*(3/2) = 9/8


That means on 17 persons, 9 are men and 8 are women.





The number of persons married should be whole numbers, so it should be divisible by 3 and by 4 (and also by 17) :


17 * 3 * 4 = 204


The population of Charlotte is 204 persons





9/17 * 204 = 108 are men


8/17 * 204 = 96 are women





Married :


108 * (2/3) = 72 men are married


96 * (3/4) = 72 women are married


It is ok because it is the same number of men and women who are married.





Number of persons married :


72 + 72 = 144
