Answer
$$665\frac{7}{8}\ pounds $$
Work Step by Step
We first subtract the two whole numbers:
$$ = 2058 - 1392 \\ 666 \ pounds $$
We now subtract the fractions:
$$ \frac{3}{8} - \frac{1}{2} \\ = \frac{3}{8} - \frac{4}{8} \\ = -\frac{1}{8}$$
Finally, adding these two values:
$$ = 666 + ( -\frac{1}{8}) \\ = 665\frac{7}{8}\ pounds $$
