Two students are talking after school:
What is the average of your grades in Math for September?
That is impossible since the year just started. You could not possiblly have that many grades.
What was the doubting student thinking of of the possible grades teachers give out in this school are 1,2,3,4,and 5; 5 being the best grade.
The average is the total score divided by the number of tests. All scores are integers, so the total score is an integer. The number of tests is an integer. What is the smallest total score that, when divided by an integer, would give 4.6?
