Fractienotatie

Fractienotatie is a mathematical notation used to represent a part of a whole. It is commonly expressed as a ratio of two integers, where the upper number is called the numerator and the lower number is called the denominator. The numerator indicates how many parts of the whole are being considered, while the denominator indicates the total number of equal parts the whole is divided into. For example, in the fraction 1/2, the numerator 1 signifies one part, and the denominator 2 signifies that the whole is divided into two equal parts.

The line separating the numerator and denominator can be written horizontally (e.g., $\frac{1}{2}$) or diagonally (e.g., 1/2). Both forms convey the same mathematical meaning. Fractions are fundamental in arithmetic and are used in various contexts, including measurements, proportions, and algebraic expressions. Understanding fractienotatie is crucial for comprehending more complex mathematical concepts. It allows for the precise representation of quantities that are not whole numbers. Different types of fractions exist, such as proper fractions (where the numerator is smaller than the denominator), improper fractions (where the numerator is greater than or equal to the denominator), and mixed numbers (which combine a whole number and a proper fraction). Operations like addition, subtraction, multiplication, and division can be performed with fractions, each following specific rules to maintain mathematical accuracy.
