Eric divided 615 by 19.68 and said the answer is 66.5.
Is his answer reasonable?
Use rounding to estimate the quotient of the decimals. The dividend 615 is close to 600, and the divisor decimal 19.68 is close to 20.
Eric's answer of 66.5 is not close to 30.
So, no, Eric's answer is not reasonable, because 615 is about 600 and 19.68 is about 20. The quotient 600 and 20 is 30, and Eric's answer is not close to 30.
