Question 702059
I'm assuming that 5:3 is the ratio of the winning team's score to the losing team's score. Therefore, the ratio of these two scores must be equivalent to 5:3, or the fractions 5/3 and winning/losing (scores) must be equal. (Ratios can be written as fractions.) Since we do not know the winning team's score, we can use a variable to stand in its place. We can solve for this variable by using cross multiplication:


5/3 = x/77
3x = 385
x ≈ 128.3 points.


Rounding down, the winning team would have 128 points if the losing team had 77 and the ratio between them is 5:3.
