    Problem Solving Question

    Hi there.

    For some reason this question (which should be easy) Just isn't clicking with me.

    "In foods class, a group of six students baked three pies. If each student ate 3/8's of the pie, how much pie is left over?"

    Answers to this Question

    A. 1 2/3
    B. 1 1/4
    C. 3/4
    D. 1/2

    Any help would be greatly appreciated.

    Re: Problem Solving Question

    Hello MathDumb.

    Let 1 pie be 8/8, 3 pies are 3*\frac{8}{8}=\frac{24}{8}, Since each child eats \frac{3}{8} of a pie, six of them would eat 6*\frac{3}{8}=\frac{18}{8}, now you can subtract part of pie that children ate from whole pie -> \frac{24}{8}-\frac{18}{8}=\frac{6}{8}=\frac{3}{4}. So the correct answer is (C).
