One-hundredth is a fractional term that represents one part of a whole divided into one hundred equal parts. It is often denoted as 1/100 or expressed as a percentage, which is 1%. This concept is commonly used in mathematics, finance, and everyday measurements, such as when calculating discounts or interest rates. In the metric system, one-hundredth is also represented by the prefix centi-, as seen in units like centimeter or centiliter. This prefix indicates that the unit is one-hundredth of the base unit, making it easier to understand and work with smaller measurements in various fields, including science and engineering.
