My question is: Yves and his siblings ordered pizza and asked to have it cut into 16 slices. During dinner time, they only ate one-fourth of it. The next day, Yves ate one-fourth of the remaining pizza. Then his two siblings ate 2 slices each. How many slices of pizza were left? Your thoughts:
During dinner time, Yves and his siblings ate 16 / 4 = 4 slices. So the next day, there were still 16 - 4 = 12 slices left. The next day, Yves ate 12 / 4 = 3 slices of pizza. Thus, there were 12 - 3 = 9 slices left. Then, his two siblings ate 2 x 2 = 4 slices of pizza. Therefore, there were still 9 - 4 = 5 slices of pizza left. The final answer: 5.
