Three friends share a sandwich that is 16 inches long and cut crosswise each friend shares an equal length of the sandwich between which two whole numbers is the number of inches of sandwich each friend gets

The length of the share of each part is between 5 and 6 inches.

Step-by-step explanation:

In order to find how long is the share of each friend we need to take the total length of the sandwich and divide it by the amount of people that will eat it. In this case the sandwich is 16 inches and it'll be divided by 3 friends. So we have:

share = length of sandwich / number of friends = 16/3 = 5.34 inches

The length of the share of each part is between 5 and 6 inches.
