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.
[tex]Average = \frac{4+3+5+2+5+5}{6} =\frac{24}{6} =4[/tex]
The three scores 5, 5, and 3 would give her an average that is a repeating decimal
[tex]Average = \frac{4+3+5+5+5+3}{6} =\frac{25}{6} =4.166667[/tex]
