Answer 1

1) $3 frac{3}{8} *3 frac{1}{5} *1 frac{5}{12} -4 frac{1}{6} *3 frac{1}{5} =$ $frac{27}{8} * frac{16}{5} * frac{17}{12} -frac{25}{6} *frac{16}{5} = frac{9}{1} * frac{1}{5} * frac{17}{2} -frac{5}{3} *frac{8}{1} = frac{153}{10}- frac{40}{3} =15 frac{3}{10} -13 frac{1}{3} =$ $14 frac{39}{30} -13 frac{10}{30} =1 frac{29}{30}$

Answer 2

3 3/6 * 3 1/5 * 1 5/12 - 4 1/6 * 3 1/5
15 26/30 - 13 2/6
15 26/30 - 13 10/30
2 16/30
