Answer key
What is in this set
- The numbers in this set run from 1 to 20.
- Every problem in it will need the divisor turned upside down.
- A careful solution takes 1 written step on average.
- The mistake this set invites most often, in 100% of the problems: the sign was changed; a reciprocal turns the fraction upside down and leaves the sign alone.
- Answers are a fraction in its lowest terms, written like 3/4.
Drawing 240 problems from this page produced 139 different ones, 58% — so a sheet of 20 will come back to a problem you have seen — there are only so many sensible ones of this kind.
