Question

what is the HCF of 3/9 and 12/19​

Answer 1

Answer:

3/171

Step-by-step explanation:

You have to use fraction formula of hcf

Hcf of fraction in form of a/b = hcf of numerator /lcm of denominator

3 = 1 x 3

12 = 1 x 3 x 4

Here 3 is the highest common factor and when we divide 3 and 12 by we get remainder as 0

HCF  of (3,12) = 3

Here 9 X 19 is number which divides 9 and 19

9 = 1 x 9

19 = 1x 19

LCM of (9,19) = 171

so ans is 3/171
