Is the student correct that a decimal point should go after the 8 in the quotient of 56.376 ÷ 8.7 = 648?

No, the decimal point goes between the 6 and 4 because if you estimate using the compatible numbers 56 ÷ 8 = 7 and 7 is very close to the answer of 6.48 which would be the most reasonable number.

Is the student correct that 4.16 ÷ 0.4 is the same as dividing 416 by 4?

Back

No, because when you move the decimal in the divisor (0.4) one time (making it 10 times bigger), you do the same to the dividend (4.16) to make it 41.6. This makes the problem easier to solve and gives you the same answer as the original problem.
