Answer
$\frac{k}{5}$-b
Work Step by Step
We are told that we are taking "the quotient of" k and 5. Thus, we divide k by 5, putting the k at the top of the fraction and the 5 at the bottom of the fraction as k was listed first. We are also, however, told that our expression should be b less than the quotient of k and 5, so we subtract b.
