Answer 1

a.

$\frac{5}{6} + \frac{1}{6} .( \frac{3}{4} - \frac{1}{5} \div \frac{4}{11} ) =$

$\frac{5}{6} + \frac{1}{6} \times ( \frac{3}{4} - \frac{1}{5} \times \frac{11}{4}) =$

$\frac{5}{6} + \frac{1}{6} \times ( \frac{3}{4} - \frac{11}{20} ) =$

$\frac{5}{6} + \frac{1}{6} \times \frac{1}{5} =$

$\frac{5}{6} + \frac{1}{30} =$

$\frac{13}{15}$

c.

$\frac{5}{2} - \frac{7}{4} - (5 - \frac{1}{4} .30 \div \frac{5}{6} ) =$

$\frac{5}{2} - \frac{7}{4} - (5 - \frac{1}{4} \times 30 \times \frac{6}{5} ) =$

$\frac{5}{2} \times \frac{7}{4} - (5 - \frac{1}{2} \times 6 \times 3) =$

$\frac{5}{2} - \frac{7}{5} - (5 - 3 \times 3) =$

$\frac{5}{2} - \frac{7}{4} - (5 - 9) =$

$\frac{5}{2} - \frac{7}{4 } - ( - 4) =$

$\frac{5}{2} - \frac{7}{5} + 4 =$

$\frac{19}{4}$
