Ben bought 1/2 pound if cheese for 3 sandwiches. if he puts the same amount of cheese on each sandwich, how much cheese will each sandwich have?

Given:
1/2 pound of cheese
3 sandwiches

To need to divide the 1/2 pound of cheese by 3 sandwiches to get the equal amount of cheese each sandwich must have.

1/2 ÷ 3 = 1/2 * 1/3 = 1/6 pound per cheese

Each sandwich contains 1/6 pound of cheese from the 1/2 pound of cheese available.
