2 students are learning how to bake apple and blueberry pies. The first student makes an apple pie and the second student bakes a blueberry pie. If the first student eats 1/4 of the apple pie and the second student eats 1/2 of the blueberry pie, which expression represents how much pie the second student ate?

a. 1/2- 1/4
b. 1/2+ 1/4
c. 2- 1/4
d. 2+ 1/2

From the information provided, the "second student ate" 1/2 of the blueberry pie. Unless you have misstated the problem, none of the alternatives apply.

Of the two pies, he ate 1/4 of the two pies. Still,none of the alternatives apply.

Recheck the problem.

To determine how much pie the second student ate, we need to subtract the portion they consumed from the total amount of pie.

Let's first find the portion the second student ate of the blueberry pie. The second student ate 1/2 of the blueberry pie.

The expression that represents how much pie the second student ate is:

1/2 - 1/4

Therefore, the correct answer is option a. 1/2 - 1/4.
