Question

(3/5 × -10/9) + (-4/5 × 1/-8)​

Answer 1

$= ( \frac{3}{5} \times \frac{ - 10}{9} ) + ( \frac{ - 4}{5} \times \frac{1}{8} ) \\ \\ = ( \frac{ - 2}{3} ) + ( \frac{ - 1}{10} ) = \frac{ - 20 + ( - 3)}{30} \\ \\ = \frac{ - 20 - 3}{30} = \frac{ - 23}{30}$

..... hope it's helpful :)

Answer 2

Answer:

$( \frac{3}{5} \times \frac{ - 10}{9}) + ( \frac{ - 4}{5} \times \frac{1}{ - 8} ) \\ \frac{ - 2}{3} + \frac{1}{10} = \frac{ - 20 + 3}{30} = \frac{ - 17}{30}$
