Kenji uses the diagram to determine the quotient of StartFraction 9 Over 10 EndFraction and Three-fifths. A fraction bar labeled 1. Under the 1 are 10 boxes labeled StartFraction 1 Over 10 EndFraction. Under the 10 boxes are 5 boxes labeled one-fifth.

He arrives at an answer of 4 and one-half. Which could be Kenji’s error?
Kenji counted by One-fifth instead of Three-fifths.
Kenji computed the division backwards, Three-fifths divided by StartFraction 9 Over 10 EndFraction.
Kenji used the wrong fractional part to represent what was left over. Instead of a number of out 2, the number should be out of 5.
Kenji used the wrong fractional part to represent what was left over. Instead of a number of out 2, the number should be out of 10.
