Answer 1

hiii!!!

here's ur answer...

$1. \: \frac{ - 2}{3} \times \frac{3}{5} + \frac{5}{2} - \frac{3}{5} \times \frac{1}{6} \\ \\ = ( \frac{ - 2}{3} \times \frac{3}{5} ) + ( \frac{5}{2} ) - ( \frac{3}{5} \times \frac{1}{6} ) \\ \\ = \frac{ - 2}{5} + \frac{5}{2} - \frac{1}{10} \\ \\ = \frac{ - 4}{10} + \frac{25}{10} - \frac{1}{10} \\ \\ = \frac{ - 4 + 25 - 1}{10} \\ \\ = \frac{20}{10} \\ \\ = 2 \\ \\ 2. \: \frac{2}{5} \times ( \frac{ - 3}{7} ) - \frac{1}{6} \times \frac{3}{2} + \frac{1}{14} \times \frac{2}{5} \\ \\ = ( \frac{2}{5} \times \frac{ - 3}{7} ) - (\frac{1}{6} \times \frac{3}{2} ) + ( \frac{1}{14} \times \frac{2}{5} ) \\ \\ = \frac{ - 6}{35} - \frac{1}{4} + \frac{1}{35} \\ \\ = \frac{ - 6 + 1}{35} - \frac{1}{4} \\ \\ = \frac{ - 5}{35} - \frac{1}{4} \\ \\ = \frac{ - 1}{7} - \frac{1}{4} \\ \\ = \frac{ - 4}{28} - \frac{7}{28} \\ \\ = \frac{ - 4 - 7}{28} \\ \\ = \frac{ - 11}{28} \\ \\ hope \: this \: helps \: u...$
