Final answer:
When you add two rational numbers, each number can be written as a fraction.
Step-by-step explanation:
When you add two rational numbers, each number can be written as a fraction. A rational number is a number that can be expressed as the quotient or fraction a/b, where a is the numerator and b is the denominator. For example, when adding the rational numbers 1/3 and 1/4, we can write them as fractions and find a common denominator, such as 12. So the sum of 1/3 + 1/4 would be 4/12 + 3/12 = 7/12.
