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. <hau> A lokacin abincin dare, Yves da 'yan uwansa sun ci 16 / 4 = 4 yanka. Ranar da ta biyo baya, har yanzu akwai 16 - 4 = 12 da suka rage.
