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
