Question

Matt had instructions to take a box of nails to a classroom that has a number equal to the remainder of the division 2960÷9. matt took the nails to class room 17. without performing calculations, tell whether matt is correct. Explain your mathematical thinking.

Answer 1

Matt is not correct

Explanation:

The remainder from division by 9 will always be a number less than 9. The number 17 is not less than 9, so Matt made an error.

_____

Matt may have tried to find the remainder by adding the digits of the dividend:

2 + 9 + 6 + 0 = 17

Matt needs to continue this process until he gets a single digit:

1 + 7 = 8

8 is the remainder from the division.
