Mrrafil [7]

On her first three 5-point math quizzes, Ami’s scores were 4,3, and 5. She will take 3 more quizzes this semester. What three scores would give her an average that is a whole number? A repeating decimal?

Answer: The three scores 2, 5, and  5 would give her an average that is a whole number.

Average = \frac{4+3+5+2+5+5}{6} =\frac{24}{6} =4

The three scores 5, 5, and 3 would  give her an average that is a repeating decimal

Average = \frac{4+3+5+5+5+3}{6} =\frac{25}{6} =4.166667
