Question

I) A number which can be written in the form of pq . Where p,q are integers and q≠0 is called a rational number.

II ) If p,q are co – primes, then pq is called standard form

The standard form of a rational number is​

Answer 1

Answer:

As you might remember, a rational number is any number that can be written as a fraction pq. Here the numerator and denominator are both integers, and q≠0. The other explanations mostly listed out specific examples of these numbers.

Step-by-step explanation:

Two integers p and q are said to be r coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1

So according to this they both have only one common factor that is 1 so HCF =1

Correct answer will be Option D
