On the third math book page 1 1 1, I asked if I ate all three kinds of moon cakes, and I just ate one together. How can I get it?

First of all, if you divide it into two parts, you can only take 1 part, which is 1/2 (if you take two parts, you can't take other moon cakes).

The remaining1-1/2 =1/2 = 2/4 needs to be taken out from the remaining moon cakes divided into 4 portions and 8 portions.

2/4 can only take 1 from the moon cakes divided into four parts, that is, 1/4 (the same reason as taking 1/2 for the first time).

There is still1-1/2-1/4 =1/4 = 2/8, so you have to take 2 mooncakes and divide them into 8 portions.
