Mrs. vargas bakes a pie for her book club meeting. the shaded part of the diagram below shows the amount of thw pie left after the meeting. this evening mr. vargas eats 1/4 of the whole pie. what fraction represents the amount of pie remaining?

I saw the figure of the pie. It is a circle with 8 slices. 4 slices are shaded, the other 4 are not.

So 4/8 or 1/2 of the pie is left. 
Mr. Vargas eats 1/4 of the whole pie. 

8 slices * 1/4 = 8/4 = 2 slices.

Out of the 4 slices remaining, Mr. Vargas ate 2 slices.

That left 2 slices from the original 8 slices.

2/8 = 1/4 of the pie remained.
