A baseball pitcher allowed 2 runs in 9 innings. At that rate, how many runs would he allow in 54 innings?

A: 65 runs
B: 12 runs
C: 27 runs
D: 6 runs

To solve this problem, we need to find the rate at which the pitcher allows runs and then apply that rate to the given number of innings.

If the pitcher allowed 2 runs in 9 innings, we can find the rate by dividing the number of runs by the number of innings:

Rate = 2 runs / 9 innings

To find how many runs the pitcher would allow in 54 innings, we can multiply the rate by the given number of innings:

54 innings * (2 runs / 9 innings) = 12 runs

Therefore, the pitcher would allow 12 runs in 54 innings.

The correct option is B: 12 runs.
