    Real life word problem 1/2x7/8

    Hi All,
    My child has a problem that I can't help him to understand.
    It will be highly appreciated if I could find a solution for this problem:
    A studnet in answering a word problem wrote 1/2x7/8
    a- Write a "real life" word problem for which 1/2x7/8 is part of the working.
    b- Draw a diagram to illustrate 1/2 x 7/8
    c- Evaluate 1/2x 7/8 "which I think this the easiest one"

    Thank you in advance

    Hi saad123,

    For a) you might be able to say something like you know the post office is 7/8 of a kilometer from your house, and that the bus stop is halfway between your house and the post office. How far is the bus stop from your house?

    Another could be "A recipe for muffins for 4 people requires 7/8 cup of flour. How much would be required if you only wanted to make muffins for 2 people?"

    Hello, saad123!

    \text{A student in answering a word problem wrote: }\,\tfrac{1}{2} \times \tfrac{7}{8}.
    \text{(a) Write a "real life" word problem for which }\tfrac{1}{2}\times\tfrac{7}{8}\text{ is part of the working.}
    Your mother baked an apple pie.
    Your father ate \tfrac{1}{8} of it.
    You and your brother will share the rest of the pie equally.
    What fraction of the pie is your share?




    \text{(b) Draw a diagram to illustrate }\tfrac{1}{2}\times\tfrac{7}{8}

    This is the pie with your father's slice removed.
    Code:
                  * * *..
              *     .:::::*.
            *       .:::::::*
           *  .     .:::::.  *
                .   .:::.
          *       . .:.       *
          * . . . . * . . . . *
          *       . . .       *
                .   .   .
           *  .     .     .  *
            *       .       *
              *     .     *
                  * * *
    This is your share of the pie.
    Code:
                ..* *
             .*:::::*
            *:::::::*       *
           *::::::::*     *  *
           :::::::::*   *
          *:::::::::* *       *
          *:::::::::* . . . . *
          *::::::::/. .       *
           :::::::/ .   .
           *:::::/  .     .  *
            *:::/   .       *
              *     .     *
                  * * *



    \text{(c) Evaluate }\tfrac{1}{2}\times\tfrac{7}{8}

    \frac{1}{2} \times \frac{7}{8} \;=\;\frac{1\times 7}{2\times 8} \;=\;\frac{7}{16}
