Question

Prove that the sum difference product of two rational number is a rational number​

Answer 1

Yes the sum of two rational number is a rational number.

Let's take an example.

1. 22+34 = 65. So, 22 and 34 are the rational numbers and 65 also a rational number.

2.

$\frac{1}{6} \: and \: \frac{1}{2} = > \: \frac{3}{6} = > \: 2$

So, similarly these are all the rational numbers.
