Answer:
4/5 slices were eaten and 1/5 slices remain
Step-by-step explanation:
If 8 slices were eaten and 2 are left, this means there were 10 slices of the pizza to begin with.
8/10, or 4/5 slices have been eaten
2/10, or 1/5 slices remain
15x - 40 = 8
3/4x-2=2/5
Multiply each side by 4*5 or 20
20 (3/4x-2=2/5)
