Final answer:
The student is asked to identify the amounts of pizza left after a party, which are 1/2 pepperoni pizza, 3/4 cheese pizza, and 5/12 vegetable pizza. Visualization using pie fractions as examples can aid in understanding these amounts.
Step-by-step explanation:
The student has asked about the amounts of different types of pizza left after a party. Specifically, there was 1/2 of a pepperoni pizza, 3/4 of a cheese pizza, and 5/12 of a vegetable pizza remaining. To determine and visualize these amounts, one can draw upon the concept of fractions just as if they were fractions of a pie. A half of a pizza is a common concept, but visualizing 3/4 and 5/12 might be a bit more complex. It's helpful to compare these to other familiar fractions, such as knowing that there are four quarters in a dollar or relating the pizza pieces to portions of a pie.
