Answer key
What is in this set
The numbers in this set run from 1 to 20.
41% of them need simplifying at the end.
A careful solution takes 2 written steps on average.
The mistake this set invites most often, in 100% of the problems: a common denominator was found first; multiplying needs none — the tops multiply and the bottoms multiply.
Answers are a fraction in its lowest terms, written like 3/4.
Drawing 240 problems from this page produced 229 different ones, 95% — so a sheet of 20 is a new sheet almost every time.
We would put this in front of a grade 5 class. That is our judgement, not a standard, and it is printed here so you can disagree with it. Everything else we put in that year.
