Question

Find the HCF of 12.25 and 2/3?
1. 1/10
2. 1/12
3. 1/15
4. 1/20

Answer 1

Correct Answer - Option 2 : 1/12

Given:

The given numbers are 12.25 and 2/3.

Formula used/Concept Used:

HCF of fraction = (HCF of numerators)/(LCM of denominators)

Calculation:

Fraction conversion of 12.25 = 49/4

HCF of numerator = HCF of (49, 2) = 1

And, LCM of denominator = LCM of (4, 3) = 12

∴ HCF of (49/4 and 2/3) = HCF of (49, 2)/LCM of (4, 3) = 1/12
