 <translate> Donna had 2 * 1 = 2 pieces of cake left. Before her snack, there were 2 + 1 = 3 pieces left. Those 3 pieces were half the leftovers, so she had 3 * 2 = 6 pieces before sharing with her brothers. Those 6 pieces were half the party leftovers, so the cake was 2 * 6 = 12 pieces before the party. So, the answer is 12. <yor> Donna ní 2 * 1 = 2 ẹyọ akara oyinbo tó kù. Ṣáájú kí wọ́n tó jẹun tán, wọ́n ti jẹ méjì àti ẹyọ kan, ìyẹn sì jẹ́ mẹ́ta.
