A rational number is a number that is of the form p/q, where: p and q are integers, q ≠ 0. Some examples of rational numbers are: 1/2, −3/4, 0.3 (or) 3/10, −0.7 (or) −7/10, etc.

To add two or more rational numbers with like denominators, we simply add all the numerators and write the common denominator. For example, add 1/8 and 3/8. Let us understand this with the help of a number line.
On the number line, we start from 1/8. We will take 3 jumps toward the right as we are adding 3/8 to it. As a result, we reach point 4/8. 1/8 + 3/8 = (1 + 3)/8 = 4/8 =1/2 Thus, 1/8 + 3/8 = 1/2.

Multiplication of Rational Numbers
Step 1: Multiply the numerators. (−2)×(−4)=8.
Step 2: Multiply the denominators. ...
Step 3: Reduce the resulting number to its lowest term.
On the number line, we start from 1/8.

Thus, 1/8 + 3/8 = 1/2.
