What is in this set

The numbers in this set run from 2 to 40.
Every problem in it will convert to a smaller unit.
A careful solution takes 1 written step on average.
The mistake this set invites most often, in 23% of the problems: going to a smaller unit gives more of them, so multiply by 10 rather than divide.
Answers are a whole number.

Drawing 240 problems from this page produced 107 different ones, 45% — so a sheet of 20 will come back to a problem you have seen — there are only so many sensible ones of this kind.
