 <translate> 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. <yor> Nígbà oúnjẹ ọ̀sán, Yves àti àwọn àbúrò rẹ̀ jẹ 16 / 4 = ìpín mẹ́rin. Nígbà tó di ọjọ́ kejì, a ṣì ní 16 - 4 = 12 ẹyọ.
