Let A be the set of all positive prime intergers less than 30. The number of different rational numbers whose numerator and denominator belong to A is

Let A = { x : x is a prime number and x lt 30 } The number of different rational numbers whose numerator and denominator belong to A is :

If A={x|x is prime number and x<30} find the number of different rational numbers whose numerator and denominator belong to A.

If A={x|x is prime number and x<30}, find the number of different rational numbers whose numerator and denominator belong to Adot

If A={x|x is prime number and x<30}, find the number of different rational numbers whose numerator and denominator belong to Adot

If A={x|x is prime number and x<30}, find the number of different rational numbers whose numerator and denominator belong to Adot

Assertion: Let A={x:x is a prime number and xlt30}. Then the number of different rational numbers, whose numerator and denominator belong to A is 93. Reason: p/q is a rational number , q!=0 and p,qepsilonZ (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not the correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

LetA={x/x is a prime number and x<30 ).The number of rational numbers whose numerator and denominator belong to A is of the form 10a+1 then a=

Write two rational numbers with numerator less than the denominator.

Write all the prime numbers less than 15.
