It matters because percentages let us quickly understand proportions—like how much of website traffic comes from different browsers—without needing to know the actual total numbers.

In mathematics, a percentage, percent, or per cent () is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign (%), although the abbreviations pct., pct, and sometimes pc are also used. A percentage is a dimensionless number (pure number), primarily used for expressing proportions, but percent is nonetheless a unit of measurement in its orthography and usage.
