Answer 1

$1 frac{3}{4} times ( - frac{2}{12} ) - frac{8}{21} times frac{2}{12} + 3frac{3}{7} = frac{1}{6} times ( - 1 frac{3}{4} - frac{8}{21} ) + 3 frac{3}{7} = frac{1}{6} times ( -1 frac{3 times 21}{84} - frac{8 times 4}{84}) + 3 frac{3}{7} = frac{1}{6} times ( - 1 frac{ - 63 - 32}{84} ) + 3 frac{3}{7} = frac{1}{6} times ( - 2 frac{11}{84} ) + 3 frac{3}{7} = - frac{179}{6 times 84} + 3 frac{3}{7} = - frac{179}{504} + 3 frac{3 times 72}{504} = 3 frac{216 - 179}{504} = 3 frac{37}{504}$

Answer 2

1 3/4-2/12-8/21*2/12+3 3/7(1 3/4-2/12*2/12)-(8/21+3 3/7)=2 1/6 + 3 1/21
