What is a percentage?

A percentage is a ratio whose second term is always 100. The term "percent" means parts per hundred. It originates from the Latin phrase per centum, which translates to "per hundred." In mathematics, the symbol % is used to denote percentages, and it can also be abbreviated as pct.
For example, 12% (read as 'twelve percent') is equivalent to:

• The fraction 12/100,
• The simplified fraction 3/25, or
• The decimal 0.12.

Percentages are commonly used to express how large or small one quantity is relative to another. They provide a standardized way to compare proportions and understand relationships between quantities.
