Question

Are there two rational numbers whose sum and product both are rational? justify​

Answer 1

Answer:

yes there are we know that all whole numbers are  rational no but all rational no are not whole numbers  so, clearly we can say that 2and 3 are whole numbers and also rational numbers  . if we multiply 2and 3 we get 6 and similarly if we  add  2+3 = 5 . so , we can say that 5and 6 are also rational numbers , because we can write 5 as 5/1 in rational no form and 6 as 6/1  both are now in ratinal form .
