What is in this set

The numbers in this set run from 1 to 20.
Every problem in it will have a whole number on one side.
A careful solution takes 3 written steps on average.
The mistake this set invites most often, in 100% of the problems: the first fraction was turned upside down instead of the second — it is the divisor that is inverted.
Answers are a fraction in its lowest terms, written like 3/4.

Drawing 240 problems from this page produced 202 different ones, 84% — so a sheet of 20 is a new sheet almost every time.

The same skill, harder or easier
