A.) Ratio of Goals by Defense to Midfielder = 3/10
So, On the Washington High Soccer team, there are (3) Goal scored by the defense for every (10) goals scored by midfielder.
B.) Number of Goals scored by Forwards = 12
Total Number of Goals = 12 + 6 + 2 + 0 = 20
So, the ratio is 12/20 = 6/10 = 3/5
In short, Your Answer for this part would be: 3:5
