Question

Why are p and q said to be mutually prime in a rational number, as -5/2 is also rational?

Answer 1

P & q are not always mutually prime or co primes in any rational number p/q.. Only when a rational number p/q is in its least form , we can say that p & q are mutually prime. Yes! 10/2 is a rational number but 10 & 2 ...

Answer 2

Answer:

Step-by-step explanation:

Mutually prime numbers means

"These two numbers are not having common factor."

For example

35=5*7

6=3*2

So here 35 and 6 are not having any common factor so 35 & 6 are co-prime

Also in 35/6 can not cut anything up and down

Next

3*5=15

2*7=14

15 & 14 are also co-prime

If p and q are not having any common factor then they are co-prime

but do not get confused with p and q

You can write a,b or x,y in place of p,q

(I hope it may clear your doubts,

still any doubt then comments are welcome)

All the best
