42/50 = 84%
A value like 42/50, or 84%, might show up as a test score, a survey result, or the battery level on a device. It tells you that most of the total is accounted for, but some is still missing.
To picture 42/50 quickly, imagine a bar split into 50 equal parts, with 42 shaded in. It’s a little more than four-fifths full, so you can estimate it as close to, but below, 85%.
A common mistake is to treat 84% as if it means 84 points out of any possible total. Percentages describe a share of a particular whole, so 84% of 50 and 84% of 100 are different amounts.
