A value like 45/87, or about 51.72%, could describe how many students in a class chose a particular lunch option or how often a bus arrived on time. It’s a little more than half, so it represents a narrow majority.

To picture it quickly, imagine 100 dots: about 52 would be shaded and 48 left unshaded. You can also think of it as just over half of a group.

One common mistake is treating 51.72% as exactly 50%, even though it is slightly higher. Also, the fraction’s numerator and denominator matter: 45 out of 87 is not the same share as 45 out of 100.
