a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.
Determine which student found the correct quotient.
b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?
Answer:
