What are Rational Numbers Online Tutoring Rational numbers are the numbers which are written in the p/q form, where p and q are any integers except q 0. The place where the number is written on the top such as p is known as the numerator and the place where the number is written in the bottom such as q is known as the denominator. Rational numbers are written in this format and they can be added, subtracted multiplied or divided. Rational numbers also represent a part of a whole and also can be reduced to their lowest fraction form. Example 1: Combine the given rational numbers, 2/3 + 4/3. Given rational numbers: 2/3 + 4/3 In order to add or subtract given rational numbers, they should always have a common denominator. In the given question, both 2/3 and 4/3 have common denominator as 3. Hence we can simply add the numbers in the numerator. This gives: 2/3 + 4/3 = (2 + 4)/3 = 6/3 The fraction 6/3 can be reduced further by dividing top and bottom by their common factor 3. Hence 2/3 + 4/3 = 6/3 = 2/1. Example 2: Combine the given rational numbers, 7/6 5/6. Given rational numbers: 7/6 5/6 In order to add or subtract given rational numbers, they should always have a common denominator. In the given question, both 7/6 and 5/6 have common denominator as 6. Hence we can simply subtract the numbers in the numerator. This gives: 7/6 5/6 = (7 - 5)/6 = 2/6. The fraction 2/6 can be reduced further by dividing top and bottom by their common factor 2. Hence 7/6 5/6 = 2/6 = 1/3.
