Answer
There are 46 hits in 161 times at bat.
Work Step by Step
Let's assume the required no of hits are x.
Now, we will write the proportion for the given details
$\frac{8 hits}{28 times-at-bat} = \frac{x hits}{161 times-at-bat}$
so. $ 8\times161= x\times 28$ (Same units cancelled)
Now divide both sides by 28.
$\frac{1288}{28} = \frac{28x}{28}$
$ x = 46 $
There are 46 hits in 161 times at bat.
