Question

3/11*(-3/5)-5/11*(-3/5)+7/22*(-3/5)​

Answer 1

$\small \bold{\frac{3}{11} \times (\frac{ - 3}{5} ) - \frac{5}{11} \times ( \frac{ - 3}{5} ) + \frac{7}{22} \times ( \frac{ - 3}{5} )}$

$= \frac{ - 9}{55} - \frac{5}{11} \times ( \frac{ - 3}{5} ) + \frac{7}{22} \times ( \frac{ - 3}{5} )$

$= \frac{ - 9}{55} - \frac{ - 3}{11} + \frac{7}{22} \times ( \frac{ - 3}{5} )$

$= \frac{6}{55} + \frac{7}{22} \times ( \frac{ - 3}{5} )$

$= \frac{6}{55} + \frac{ - 21}{110}$

$= \frac{ - 9}{110}$
