Math problem in the third grade of primary school: two sisters collect stamps. My sister collects four times as many stamps as her sister. My sister also has 69 more stamps than her sister. How many stamps have the two sisters collected? 69÷(4- 1)=69÷3=23 (pieces)

23*4=92 (piece)

A: My elder sister is 92 yuan and my elder sister is 23 yuan.

My sister collects stamps four times as much as my sister, that is, my sister collects stamps three times as much as my sister, 69 more than my sister. So as long as you divide 69 by 3, it means your sister has a ticket.
