Exact
$(50 \times 4) - 68 \frac{1}{2} - 76 \frac{5}{8} - 33 \frac{1}{4}$ =
$200 - 68 \frac{4}{8} - 76 \frac{5}{8} - 33 \frac{2}{8}$ =
$199 \frac{8}{8} - 68 \frac{4}{8} - 76 \frac{5}{8} - 33 \frac{2}{8}$ =
$131 \frac{4}{8} - 76 \frac{5}{8} - 33 \frac{2}{8}$ =
$130 \frac{12}{8} - 76 \frac{5}{8} - 33 \frac{2}{8}$ =
$54 \frac{7}{8} - 33 \frac{2}{8}$ =
$21 \frac{5}{8}$
