Question

if a,b are co primes then the H.C.F of a/b , b/a is
a) 1
b) 1/ab
c) a/b
d) b/a
answer it fast I will mark it as blainliest answer...​

Answer 1

Answer:

c. answer

coprime means two number only have one in common between both

so a=a*1

b=b*1

now a/b is appropriate ans

Answer 2

Given :  a,b are co primes  

To Find:  H.C.F of a/b , b/a  

a) 1

b) 1/ab

c) a/b

d) b/a

Solution:

HCF of fractions = HCF of numerators/LCM of the denominators

a,b are co primes  

HCF ( a , b) = 1

LCM (a , b)  = ab

a/b , b/a

Numerators are a and b

Denominators are b and a

HCF of numerators = HCF ( a , b) = 1

LCM of the denominators = LCM (a , b)  = ab

HCF of fractions =  1/ab

Correct option is b)
