Question

Annie needs to solve 855 divided by 19 she thought she would solve 855 divided by 20 and then adjust since 20 is an easier number to work with than 19. Can she solve the problem this way? Why or why not? Show your work

Answer 1

The answer to this question would be yes.

Answer 2

Yes, she can. Dividing by 20 gives 1 less every time, so you can just add to the result you get when you divide 855 from 20.
