törtszámokat

Törtszámokat, often translated as fractions, represent parts of a whole. A törtszám consists of two parts: a numerator and a denominator, separated by a line. The denominator indicates the total number of equal parts the whole is divided into, while the numerator specifies how many of those parts are being considered. For example, 1/2 represents one out of two equal parts, meaning half of the whole.

Törtszámokat can be used to express quantities that are not whole numbers. They are fundamental in mathematics and appear in various contexts, from simple measurements to complex calculations. Addition and subtraction of törtszámokat require a common denominator, meaning the denominators of the fractions must be the same before the numerators can be added or subtracted. Multiplication of törtszámokat involves multiplying the numerators together and the denominators together. Division of törtszámokat is performed by inverting the divisor (the second fraction) and then multiplying.

Fractions can be proper or improper. A proper fraction has a numerator smaller than its denominator, representing a value less than one. An improper fraction has a numerator equal to or greater than its denominator, representing a value of one or more. Improper fractions can be converted into mixed numbers, which consist of a whole number and a proper fraction. Understanding törtszámokat is crucial for developing a strong foundation in arithmetic and algebra.
