Rational numbers are numbers that can be expressed as a fraction, where both the numerator and denominator are integers. Operations with rational numbers include addition, subtraction, multiplication, and division. When adding or subtracting rational numbers, it’s essential to have a common denominator. For example, to add 1/4 and 1/2, you can convert 1/2 to 2/4, making it easy to add: 1/4 + 2/4 = 3/4. Multiplying rational numbers is straightforward; simply multiply the numerators and denominators. For instance, 2/3 multiplied by 3/5 equals (2 x 3) / (3 x 5) = 6/15, which can be simplified to 2/5. Division involves multiplying by the reciprocal, so dividing 1/2 by 1/3 means multiplying 1/2 by 3/1, which gives 3/2. Understanding these operations allows you to work confidently with rational numbers.
