Answer
$\dfrac{3}{2k}+\dfrac{7}{2h}-\dfrac{7}{4hk}$
Work Step by Step
Dividing the denominator to each of the terms of the numerator, the given expression, $
\dfrac{24h^2k+56hk^2-28hk}{16h^2k^2}
,$ simplifies to
\begin{array}{l}\require{cancel}
\dfrac{24h^2k}{16h^2k^2}+\dfrac{56hk^2}{16h^2k^2}-\dfrac{28hk}{16h^2k^2}
\\\\=
\dfrac{3}{2k}+\dfrac{7}{2h}-\dfrac{7}{4hk}
.\end{array}
