Estimate 140 pounds Exact $140 \frac{1}{24}$ pounds
Estimate $10 + 85 + 37 + 8 = 140$ Exact $10 \frac{3}{8} + 84 \frac{1}{2} + 36 \frac{5}{6} + 8 \frac{1}{3}$ = $9 \frac{11}{8} + 84 \frac{4}{8} + 36 \frac{5}{6} + 8 \frac{2}{6}$ = $93 \frac{15}{8} + 44 \frac{7}{6}$ = $94 \frac{7}{8} + 45 \frac{1}{6}$ = $94 \frac{21}{24} + 45 \frac{4}{24}$ = $139 \frac{25}{24}$ = $140 \frac{1}{24}$ =
