4-46.

Kenali wants to cut a piece of rope into three equal pieces, and she wants to have a -foot piece remaining. Help her figure out how long to make each of the three equal pieces for each total length of rope given below.

  1. A -foot piece of rope (find ).

    First, subtract from to find the amount left for the three equal parts.

    Next, determine how long each of the three pieces will be. If three pieces must add together to be feet, how long are they?

    feet

  2. A -foot piece (find ).

    The process for solving this problem is the same as in part (a).
    Remember to subtract feet from the total before dividing it into three parts.

    feet

  3. A -foot piece (find ).

    Follow the steps outlined in part (a).
