[1] First, remember that the sum of the angles in a triangle must add up to 180*.
[2] We are told two of the angles, 44* and 66*, but we are missing the third.
[3] Combining [1] and [2], we know that 44* + 66* + ? = 180*. In other words,
110* + ? = 180*
so,
? = 70*
The missing angle 3 is equal to 70 degrees.
Play ground 70% (TOTAL)
books 30% (TOTAL)
60% of the 70% are boys
20% of the 30% are boys
Does that sound about right for a start?
We will guess and check to solve this problem
504/9= 56
504/8= 63
504/7= 72
504/6= 84
.....
we can continue the pattern. However, we know that 50 is the product of 8 and 7, so we can use that number
9*8*7=504
The fraction of boys to total students would be 5/8
The fraction of boys to girls would be 5/3
