Answer 1

Answer:

Answer is in explanation

Step-by-step explanation:

It is quiet easy.

If we add a rational number(all rational numbers have end) and a irrational number(all irrational numbers have no end) then answer will be irrational.

For eg.

If we were to add 5(rational) with 3.333333333333...(irrational) it is still a irrational number as the threes after points will continue. and will make the answer like this 8.33333333333333333

You could take an example like this and show it to your teacher.
