45/72 = 62.5%
A value like 45/72, or 62.5%, can show up when 45 out of 72 people choose a certain option in a survey. It could also describe finishing 45 of 72 tasks, answering 45 questions correctly, or having 45 seats filled in a theater with 72 seats.
To picture 45/72 quickly, think of a little more than three-fifths of a whole. It is also exactly five-eighths, so you can imagine dividing something into eight equal parts and shading five of them.
A common mistake is to assume that 45/72 is close to 45%, because the numerator is 45. The denominator matters too: it represents the total, so the same 45 would describe a different percentage out of 100, 72, or 50.
