1)  

 Which of the following is a rational number





Answer: 4


 
 


SOLUTION 1 :

Rember:

Rational numbers can be writtenas ab

(where a and b are integers and b is not zero).When written as decimals , rational numbers terminate or repeat.

Irrational numbers cannot be written as ab
( where a and b are integers and b is not zero). When written as decimals , irrational numbers do not terminateor repeat.
 
Solve:
3 can be written as 31  which is afraction. So,3 is a rational number.
 
6 can be written as 61  which is afraction. So,6 is a rational number.
 
7 can be written as 71  which is afraction. So,7 is a rational number.
 
the rational numbers are 3, 6, 7 
 
So, answer is all the choice is correct
