Answer:

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!!!
