Question

Verify
2/3 * [-6/7 + 4/5] = [2/3 * 4/5] *
-6/7​

Answer 1

Answer:

$\frac{2}{3} \times ( \frac{ - 6}{7} + \frac{4}{5} ) = ( \frac{2}{3} \times \frac{4}{5} )\frac{ - 6}{7} \\ \frac{2 \times - 6}{3 \times 7} + \frac{2 \times 4}{3 \times 5} = \frac{8 \times - 6}{15 \times 7} \\ \frac{ - 12 + 8}{21 + 15} = \frac{ - 48}{105} \\ \frac{ - 4}{36} = \frac{ - 48}{105} \\ \frac{ - 2}{18} = \frac{ - 16}{35} \\ hence \: \frac{ - 2}{18}is \: not = \frac{ - 16}{35}$
