We are told that Emerson struck out 112 times in 350 at-bats. We are asked to find the percent of strike outs per at-bat.

Let us find out 112 is what percent of 350.

$\text{Percentage of strike outs per at-bat}=\frac{112}{350} \cdot 100$

$\text{Percentage of strike outs per at-bat}=0.32 \cdot 100$

$\text{Percentage of strike outs per at-bat}=32$

Therefore, Emerson struck out 32% of the at-bats.
