Answer:
Step-by-step explanation:
I guess
When dividing by a fraction you flip the second fraction over and change to multiply.
The error was simplifying the -36 and the 28
That shouldn’t have been done. After flipping the fraction over they should have multiplied across:
-36/1 x 6/28 = (-36 x 6) / (1 x 28) = -216/28
Rewrite as: -7 5/7
