A fraction is a mathematical expression that represents a part of a whole. It consists of two numbers, a numerator and a denominator, separated by a horizontal line. The numerator represents the number of equal parts being considered, while the denominator represents the total number of equal parts that make up the whole.For example, in the fraction 3/8, the numerator is 3, indicating that we are considering 3 parts out of the whole, and the denominator is 8, indicating that the whole is divided into 8 equal parts.Fractions can represent numbers that are less than, equal to, or greater than one. For example, 1/2 represents half of a whole, 1/4 represents one quarter, and 3/2 represents one and a half.Fractions can be added, subtracted, multiplied, and divided just like whole numbers, using specific rules and operations. They can also be converted to decimal and percentage forms for easier comparison and calculation.Fractions are commonly used in everyday life, such as cooking recipes, measuring lengths or quantities, and calculating discounts or proportions. They are also fundamental in advanced mathematical concepts and applications.
