The correct interpretation of the sentence "If an apple is divided into one portion, there is 1 apple" is that 1 apple is divided into 1 portion on average, and each portion is 1 apple; You confuse the total number of 1 apple with the meaning of 1 apple per serving in this formula. In fact, the units of these two quantities are different. The unit of the total is "piece", and the unit of each piece is "piece/piece", just like the difference between the units of distance and speed. There is no key distinction in the primary school stage, and the middle school stage is very clear.

Therefore, the following question arises: "When an apple is divided into 0. 1 serving, it becomes 10 apples". -Its significance is that the total number of apples is 1, which is divided into 0. 1 portion on average, and each portion is 10 apples. This formula is written as follows: 1÷0. 1= 10 (per sheet)
