Answer key
What is in this set
The numbers in this set run from 1 to 9.95.
Every problem in it will have a different number of decimal places on each side.
A careful solution takes 3 written steps on average.
The mistake this set invites most often, in 100% of the problems: the numbers were lined up by their last digit instead of by the decimal point — the points have to sit one above the other, and the short one gets a zero.
Answers are a decimal.
Drawing 240 problems from this page produced 240 different ones, 100% — 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.
