A value like 31/45, or about 68.89%, could describe the share of students who passed a test, the amount of a phone battery remaining, or the percentage of a survey group choosing one option. It represents a little more than two-thirds of the whole.

A common mistake is treating 31/45 as if it were 31/100, which would make the value seem much smaller. It is also easy to confuse the numerator and denominator, even though the denominator, 45, tells you the total number of equal parts.
