Answer 1

$6 \frac{3}{20} \div ( - 8 \frac{1}{5} ) + 2 \frac{5}{7} = \frac{123}{20} \div ( - \frac{41}{5} ) + \frac{19}{7} = \frac{123}{20} \times ( - \frac{5}{41} ) + \frac{19}{7} = - \frac{3}{4} + \frac{19}{7} = - \frac{3 \times 7}{4 \times 7} + \frac{19 \times 4}{7 \times 4} = \frac{-21 + 76}{28} = \frac{55}{28} = 1 \frac{27}{28}$
