Answer 1

Answer:

a rational no. should not have denominator as 0 ... so (4-16/0) is not a rational no.

otherwise other all are rational nos.

Answer 2

A rational number in the form of p/q ,where 'p' and 'q' are integers and q ≠ 0 ,it is called rational number.

Therefore;- 1= 8/19

2=0/7

3=7/9

5=6/12

6=8/17, are rational number.

and , whose denominator is 0 is not rational number.

Since:- 4=16/0 is not rational number.
