first of all mulitply all the no.s one by one which are under bracket and then open the bracket .
take out the lcm of the denominators and then multiply it with the times of numerator . the LCM will be 120 . after that solve the equation .the answer is -137 / 120

Hey friend,
Here is the answer you were looking for:
( \frac{3}{5}  \times  -  \frac{10}{9} ) + ( -  \frac{4}{5}  \times  \frac{1}{ - 8} ) - ( \frac{2}{5}  \times  -  \frac{15}{16} ) \\  \\  =  (\frac{3 \times  - 10}{5 \times 9} ) + ( \frac{ - 4 \times 1}{5 \times  - 8} ) - ( \frac{2 \times  - 15}{5 \times 16} ) \\  \\  = ( \frac{1 \times  - 2}{1 \times 3} ) + ( \frac{ - 1 \times 1}{5 \times  - 2} ) - ( \frac{1 \times  - 3}{1 \times 8} ) \\  \\  =  (\frac{ - 2}{3} ) + ( \frac{ - 1}{ - 10} ) - ( \frac{ - 3}{8} ) \\  \\  = ( \frac{ - 2}{3} ) + ( \frac{1}{10} ) - ( \frac{ - 3}{8} ) \\  \\  =  \frac{ - 2}{3}  +  \frac{1}{10}   +  \frac{3}{8} \\  \\  taking \: lcm \: we \: get  \: 120 \\  \\  =  \frac{ - 2 \times 40 + 1 \times 12 + 3 \times 15}{120}  \\  \\  =  \frac{ - 80 + 12 + 45}{120}  \\  \\  =  \frac{ - 80 + 57}{120}  \\  \\  =  \frac{ - 23}{120}

Hope this helps!!!!
