Question : What is the HCF of 1.05 and 6.23?
Option 1: 0.89
Option 2: 0.21
Option 3: 0.07
Option 4: 0.35
Correct Answer: 0.07
Solution :
1.05 = $\frac{105}{100}$
6.23 = $\frac{623}{100}$
HCF of fractions = $\frac{\text{HCF of numerator}}{\text{LCM of denominator}}$
HCF of $\frac{105}{100}$ and $\frac{623}{100}$ = $\frac{7}{100}=0.07$
Hence, the correct answer is 0.07.
