the correct question is
A baseball team has three different pitchers. Randy pitched 3 innings and allowed 2 runs, Felix pitched 5 innings and allowed 4 runs, and Johan pitched 7 innings and allowed 5 runs.
Which pitcher has the lowest number of runs allowed per inning?
we have that
we calculate the number of runs allowed in 1 inning
if Randy pitched 3 innings and allowed ------------2 runs
in 1 inning-----------------------------------> X
X=2/3----------> 0.67 runs
if Felix pitched 5 innings and allowed-------------> 4 runs
in 1 inning-----------------------------------> X
X=4/5----------> 0.80 runs
if Johan pitched 7 innings and allowed-------------> 5 runs
in 1 inning-----------------------------------> X
X=5/7----------> 0.71 runs
the answer is
Randy has the lowest number of runs allowed per inning with 0.67
