Answer 1

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