Answer:
(81/49)
Step-by-step explanation:
First, you would find the reciprocal of the second number, (-7/9), which is (9/-7)
Then, you can multiply the numerators and denominators.
9 times 9 is 81.
7 times -7 is -49.
The answer is (81/49), which is about 1.653.
It does make a difference when it is negative because a positive number times a negative number is always a negative number.
