Operations on rational numbers, which are any numbers expressible as a ratio of two integers (p/q, where q ≠ 0), include addition, subtraction, multiplication, and division. To perform these operations, you generally work with rational numbers as fractions, finding common denominators for addition and subtraction, and multiplying numerators and denominators for multiplication. Division is performed by multiplying the first rational number by the reciprocal of the second.
