Detailed Solution

Here, we are given a statement, sum of two rational numbers is always a rational number.
We have to state if this is true or not.
It’s a property of rational numbers that they are closed under addition.
This means that whenever we add two or more rational numbers, the obtained sum is also a rational number.
Example:
1 2 + 2 3 = 3+2 6 = 5 6
So, we observe that adding 1 2 and 2 3 gives the sum as 5 6 , which is a rational number as it is in the form of a fraction.
Hence, the statement is true.   Hence, the correct option is (1).
