The Lappans buy three large sandwich wraps to serve at a picnic. Nine people in all will be at the picnic. Show three different ways to cut the sandwiches so that each person gets an equal share.
To solve this problem, we need to divide the three sandwich wraps into equal portions for the nine people. Here are three different ways to cut the sandwiches:
1. Method 1:
- Cut each sandwich wrap into 9 equal parts.
- Give each person one part from each of the three wraps.
2. Method 2:
- Cut each sandwich wrap into 6 equal parts.
- Give each person two parts from each of the three wraps.
3. Method 3:
- Cut one sandwich wrap into 3 equal parts.
- Cut the other two sandwich wraps into 6 equal parts each.
- Give each person one part from the first wrap and two parts from each of the other two wraps.
By following one of these methods, you can ensure that each person receives an equal share of the sandwiches at the picnic.
I will assume that all the sandwiches are the same size! And that they are basically cylinders.
cut each sandwich lengthwise into three parallel strips of equal size. This is a bit awkward, since the center strip will have more filling and less bread. I guess you could unroll them, spread out the fillings evenly, and then cut them.
cut each sandwich crosswise into equal lengths
slice the sandwiches diagonally, so that each piece weighs the same. Again, there's the bread/filling problem.
