    There are 396 persons in the theater. If the ratio of women to men in 2:3 and the ratio of men to children is 1:2, how many men are in the theater? I got 198 men

    If the ratio of men to children is 1:2, then there would be 396 children. 396 + 198 exceeds the number of people in the theater.

    Whatever this calculation is, it does not take the women present into account. |dw:1380605085504:dw|

    Well, it's not by guessing although if you post the options we can determine the numbers that best fit the requirements of the problem.

    It's going on 2 a.m. where I am. I have to re-work this problem so you catch some ZZZs, and I'll try to post a solution.

    I now have 108 men. Let x = number of women Let y = number of men Let z = number of children (x + y + z = 396) (3x = 2y) (z = 2y) ------------ Solve simultaneously. Women: 72 Men: 108 Children: 216 I am now going to work on a solution that does not involve three equations in three unknowns.

    Another Solution: Ratio of W:M = 2:3 Ratio of M:C = 1:2. A ratio of 1:2 is the same as a ratio 3:6 Therefore, the extended ratio of W:M:C = 2:3:6 So, 2x + 3x + 6 x = 396 11x = 396 x = 36 Men = 3*36 = 108 ---> Number of Men @ineedyouubiebs
