Question

Using appropriate properties find: 2/5 ×(-3/7) -1/14-3/7×3/5

Answer 1

Answer:

$\frac{2}{5} \times \frac{ - 3}{7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5}= \frac{ - 1}{2}$

Step-by-step explanation:

To solve using appropriate properties find: 2/5 ×(-3/7) -1/14-3/7×3/5

apply BODMAS Rule

$\frac{2}{5} \times \frac{ - 3}{7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5} \\ \\ = > \frac{ - 6}{35} - \frac{1}{14} - \frac{9}{35} \\ \\ = > \frac{ - 12 - 5 - 18}{70} \\ \\ = \frac{ - 35}{70} \\ \\ = \frac{ - 1}{2}$

Hope you understand.
