Five students decide to order a pizza. If the pizza is cut into 8 slices, will they be able to get the name number of slices without any pizza left over? How do you know?
5/8 cannot be simplified. Everyone gets a slice, but 3 pieces are left over. You have 10 fingers. 5 on each hand. Therefore, you know that 8 is 2 less than 10 and cannot be split between 5 people without leftovers.
