please solve this using suitable property​

Answer 1

Answer:

$-\frac{5}{11}$

Step-by-step explanation:

$-\frac{4}{5} \times \frac{2}{7} +\frac{3}{5} \times \frac{1}{77} -\frac{2}{7} \times \frac{9}{11}$

$=\frac{1}{5} (-4\times \frac{2}{7} +3\times \frac{1}{77} )-\frac{2}{7} \times \frac{9}{11}$ → Taking $\frac{1}{5}$ Out

$=\frac{1}{5} \times \frac{-88+3}{77} -\frac{18}{77}$

$=\frac{-85}{5\times 77} -\frac{18}{77}$

$=\frac{-17-18}{77}$

$=-\frac{35}{77}$

$=-\frac{5}{11}$
