Question : HCF of $\frac{3}{4},\frac{15}{16}$, and $\frac{18}{5}$ is:
Option 1: $\frac{3}{80}$
Option 2: $\frac{18}{5}$
Option 3: $\frac{5}{16}$
Option 4: $\frac{15}{16}$
Correct Answer: $\frac{3}{80}$
Solution :
Given numbers are $\frac{3}{4},\frac{15}{16}$ and $\frac{18}{5}$
So, HCF of $\frac{3}{4},\frac{15}{16},$ and $\frac{18}{5}$
= $\frac{\text{HCF of 3, 15, and 18}}{\text{LCM of 4, 16, and 5}}$
= $\frac{3}{80}$
Hence, the correct answer is $\frac{3}{80}$.
