Answer:
Step-by-step explanation:
You need to set up a proportion
Let x = NK
7/13 = x/56 Notice that the longest side of the small trapezoid is the denominator of the fraction on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.
Cross multiply
13x = 7*56 Combine the right
13x = 392 Divide by 13
x = 392/13
x = 30.15
NK = 30.15
For a fixed total number of boys and girls, there is only one possible answer. The boys to girls ratio is 3:2, which means 3/5 are boys and 2/5 are girls. If the total number of boys and girls is N, then
number of boys = (3/5)N
number of girls = (2/5)N
Obviously, N must be a multiple of 5, since we cannot have "fractional" boys or girls.
