c. step three
Step-by-step explanation:
CORRECT WAY
step one: -7/ -2 / 4/9 (flip 4/9)
step two: -7/-2 * 9/4 (simplify)
step three: = 63/8
Step three is incorrect because it's not - it's positive.
She forgot that a negative divided by a negative is a positive.
So -7/-2 is the same as 7/2
Hope this helps ya!!!
