Fractionaaliset

Fractionaaliset, also known as fractional numbers or fractions, are numbers that represent parts of a whole. They consist of two integers: a numerator and a denominator. The numerator represents the number of equal parts being considered, while the denominator indicates the total number of parts that make up the whole. For example, in the fraction 3/4, the numerator is 3, and the denominator is 4, meaning that three out of four equal parts of the whole are being considered.

Fractions can be classified into two main types: proper and improper. A proper fraction is one where the numerator is less than the denominator, representing a part of a whole. An example of a proper fraction is 5/7. An improper fraction, on the other hand, is one where the numerator is greater than or equal to the denominator, representing a whole number or more. An example of an improper fraction is 9/4.

Fractions can also be converted into decimal numbers and percentages. To convert a fraction to a decimal, divide the numerator by the denominator. For example, 3/4 as a decimal is 0.75. To convert a fraction to a percentage, multiply the decimal equivalent by 100. So, 3/4 as a percentage is 75%.

In mathematics, fractions are fundamental to many concepts, including addition, subtraction, multiplication, and division of rational numbers. They are also used in various real-world applications, such as measuring ingredients in recipes, calculating distances, and determining probabilities. Understanding fractions is essential for developing a strong foundation in mathematics and for solving practical problems in everyday life.
