Murtolukku

Murtolukku is the Finnish term for a fraction, a number that expresses the ratio of two integers, a numerator and a denominator, with the denominator nonzero. As a rational number, a murtolukku can be written in the form a/b, or described as the quotient a ÷ b, where a and b are integers and b ≠ 0.

Fractions can be reduced to simplest form by dividing the numerator and the denominator by their greatest common divisor. They are classified as proper (a < b), improper (a ≥ b), or mixed when written as an integer part plus a proper fraction. Fractions that have the same value are called equivalent fractions, such as 1/2 and 2/4.

Operations on fractions include addition and subtraction (requiring a common denominator), multiplication (multiplying numerators and denominators), and division (multiplying by the reciprocal). Understanding equivalent fractions and simplification helps in performing these operations efficiently.

A fraction can be expressed as a decimal, with rational decimals that terminate or repeat. Fractions can also be converted to percentages by multiplying by 100. In practical use, fractions appear in measurements, recipes, and ratios, and they form a foundational concept in arithmetic and algebra.

Terminology: the standard Finnish word is murtoluku. The form murtolukku may appear in informal writing or as a misspelling. Related topics include rational numbers, decimals, percentages, and mixed numbers.
