    Rational numbers are numbers that can be expressed as the ratio of two integers. In other words, they are numbers that can be written in the form a/b, where a and b are integers and b is non-zero. For example, 3/4, 22/7, and 11/2 are all rational numbers. The key characteristic of rational numbers is that they can be expressed in this fractional form, making them a fundamental building block of mathematics. Rational numbers can be added, subtracted, multiplied, and divided just like integers, making them a versatile and powerful tool for solving mathematical problems.
