Problem
Peter's family ordered a 12-slice pizza for dinner. Peter ate one slice and shared another slice equally with his brother Paul. What fraction of the pizza did Peter eat?
Solution 1
Peter ate slices. The pizza has slices total. Taking the ratio of the amount of slices Peter ate to the amount of slices in the pizza, we find that Peter ate of the pizza.
Solution 2
An alternative way of solving this problem is to add the slices separately. When Peter takes a full slice, he takes of the pizza. When he shares the slice with paul, he splits a slice of pizza into two, the equation is of , which is . Adding gives:
