Answer:
532 of both genders.
Explanation:
The ratio of men to women is 3:4
The ratio of men to men and women is 3/(3 + 4) = 3 / 7
So the proportion looks like this
3 /7 =228 / x
The left hand side is men to everyone. The right hand side is the actual number of men to the total number of everyone.
Cross multiply
3*x = 7 * 228 Multiply the right side
3*x = 1596 Divide by 3
3x/3 =1598/3 Combine
x = 532 Total of both men and women
