Question

Simplify using appropriate properties -: ( 3/5 × −2/7 ) − ( 1/20) − ( 2/7 × 4 /5 )

Answer 1

Answer:

$- \frac{9}{20}$

Step-by-step explanation:

$( \frac{3}{5} \times - \frac{2}{7} ) - ( \frac{1}{20} ) - ( \frac{2}{7} \times \frac{4}{5} ) \\ \\ \frac{3}{5} \times - \frac{2}{7} - \frac{1}{20} - \frac{2}{7} \times \frac{4}{5} \\ \\ \frac{ - 2}{7} ( \frac{3}{5} + \frac{4}{5} ) - \frac{1}{20} \\ \\ \frac{ - 2}{7} \times \frac{7}{5} - \frac{1}{20} \\ \\ - \frac{2}{5} - \frac{1}{20} \\ \\ - \frac{8}{20} - \frac{1}{20} \\ \\ - \frac{9}{20}$
