7△÷9=○……□
Where ○ is the quotient and □ is the remainder, and the maximum remainder is required.
Since the dividend is 7△, ○ can only be 7 or 8. If it is 8, then 7△ must be 72.
Between 0 and 79, taking 79 as an example, the maximum residue is 7. namely
79÷9=8……7
But if χ is 7, then its maximum remainder should be less than the divisor 1, that is, 9- 1=8, so it is.
The divisor should be:
7×9+8=7 1
So the answer should be: 719 = 7 ... 8.
Therefore, the two generations of love initially took out 7 1 apple and distributed it to 9 people on average, with 7 apples per person and the rest.
Leave the fruit to two generations, and the two generations will get eight apples instead.
