A fraction is a way to represent a part of a whole. It consists of two numbers: the numerator, which is the top number, and the denominator, which is the bottom number. The numerator indicates how many parts we have, while the denominator shows how many equal parts the whole is divided into. For example, in the fraction 3/4, the numerator is 3, meaning we have three parts, and the denominator is 4, meaning the whole is divided into four equal parts. Fractions can be used in various situations, such as cooking, measuring, and dividing items. They can also be classified into different types, including proper fractions, where the numerator is less than the denominator, and improper fractions, where the numerator is greater than or equal to the denominator. Understanding fractions is essential for performing basic arithmetic and solving real-life problems involving parts and wholes.
