It should be noted that there is a difference between "average" and "average score".
For example, four children ate 28 cookies. How many biscuits did each of them eat on average? 28 ÷ 4 = 7 (block). There is "7 yuan per person" here, but not everyone really eats 7 yuan. There may be eight or six dollars. This is an "average" problem.
Change it to "Divide 28 cookies among 4 children equally. How many cookies are each?" It's still 28 ÷ 4 = 7 (blocks), but it must be 7 blocks for each person when it is divided. This is an "average score" problem.
