Book Free DemoAddition of rational numbers with the same denominator
When we have the same denominators, all we have to do is add the numerators and write the answer with the resultant numerator and same denominator.
Example:
Addition of rational numbers with different denominators
We have to convert the different denominators to the same denominator. To do that, take the LCM of the denominator, then multiply both rational numbers by the LCM so that we get the equivalent rational numbers with the same denominator.
Example:
The sum of the two opposite numbers is zero.
Example:
\(- 3 + 3 = 0\ \)
\(6 + (- 6) = 0\)
