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. <hau> Donna yana da 2 * 1 = 2 guda na cake bar. Kafin abincin ta, akwai guda 2 + 1 = guda 3 da suka rage.
