A value like 34/42, or about 80.95%, could describe getting 34 questions right on a 42-question quiz. It might also represent how much of a task is finished or how many people in a group chose a certain option.

To picture it quickly, think of about four-fifths of a whole. That’s a little more than 80 out of every 100, so most of the whole is covered, with a smaller part left over.
