At this time, I proposed: "We divide this cake into ten parts on average, and each person's cake share accounts for one tenth of the total cake, which is only fair."
"Yes, but what if one tenth of each person is not enough to eat?"
"Then use another method. Everyone cuts as much as possible according to their own appetite, so that no one will have any objection."
In this way, we shared the cake. We ate the cake and were very happy. The birthday party soon ended and everyone went home happily.
Birthday parties let me know how important math is. Only by learning math well can I show myself in front of others.
