A. The proportion can be expressed as follows; 112 / 350 = x / 100
B. The percentage of times at bat that Emerson actually hit the ball is 68%
How do we find the proportion and percentage?
A. Using total strikeouts and at-bats
Total strikeouts: 30 + 40 + 42 = 112
Total at-bats: 90 + 120 + 140 = 350
the proportion would be:
112 / 350 = x / 100
x = (112 × 100)/350
x = 32
B. Since we already know from the previous calculation that Emerson hit the ball 68% of the time, the strikeout percentage is 100% − 32% = 68%
