Final answer:
Pamela has eaten 4/7 of her pizza pie, so to find the remaining part, we subtract that from the whole pizza pie (7/7), which leaves us with 3/7 of the pizza pie remaining.
Step-by-step explanation:
The student's question pertains to understanding how much of a pizza pie remains after a certain portion has been eaten. Pamela has a 4/7 eaten pizza pie, and we need to determine what fraction of the pizza is left. To find the remaining part of the pizza, we subtract the eaten fraction from the whole, which is 1 (or 7/7 since we're discussing sevenths). So, 7/7 minus 4/7 equals 3/7. Thus, 3/7 of Pamela's pizza pie is left.
