Answer 1

Answer:

$- 2 \div 3 \times - 3 \div 5 + 5 \div 2 \times 3 \div 5 \times 1 \div 6 \\ = \frac{ - 2}{3} \times \frac{ - 3}{5} + \frac{5}{2} \times \frac{3}{5} \times \frac{1}{6} \\ = ( \frac{ - 2}{3} \times \frac{ - 3}{5} ) + ( \frac{5}{2} \times \frac{3}{5} \times \frac{1}{6} ) \\ = \frac{2}{5} + \frac{1}{4} \\ = \frac{8 + 5}{20} \\ = \frac{13}{20}$
