Final answer:
To divide fractions, multiply the first fraction by the reciprocal of the second fraction.
Step-by-step explanation:
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and the denominator. So, 39/8 divided by -(65/56) can be written as 39/8 multiplied by -(56/65).
Now, multiply the numerators (39 and 56) to get the new numerator and multiply the denominators (8 and 65) to get the new denominator.
Therefore, the final answer is -(39 x 56) / (8 x 65).
