Answer
Maximum weight $=8\frac{1}{4}$ pounds
Minimum weight $=6\frac{1}{4}$ pounds
Work Step by Step
Maximum weight:
$1\frac{1}{8} + 1\frac{1}{8} + 2\frac{1}{2} + 3\frac{1}{2}$
$= 2\frac{2}{8} + 6$
$=8\frac{2}{8}$
$=8\frac{1}{4}$
Minimum weight:
$ 1 + 1 + 1\frac{3}{4} + 2\frac{1}{2}$
$= 3\frac{3}{4} + 2\frac{1}{2}$
$= 6\frac{1}{4} $
