Step-by-step explanation: To solve this problem, we need to use the order of operations (PEMDAS). First, we need to perform the division operation inside the parentheses: (-3/16)(-5/7)=-105/108. Then, we multiply the result by the first fraction: (-105/108)(5/16)=-775/1728. Finally, we subtract the result from the original expression: (-775/1728)-(-3/16x(-5/7))=-775/1728+3/16x(-5/7)=-775/1728+35/168=(-35/168)+775/1728.
