Final answer:
To subtract fractions, find a common denominator and subtract the numerators.
Step-by-step explanation:
To subtract fractions, we need to have a common denominator. In this case, the common denominator is 56. To find the difference, we subtract the numerators:
(-39/56) - (22/35) = (-39*35)/(56*35) - (22*56)/(35*56) = -1365/1960 - 1232/1960 = (-1365 - 1232)/1960 = -2597/1960
The answer, written as a reduced fraction, is -2597/1960.
