Question : The LCM of $\frac{3}{8}, \frac{5}{16},$ and $\frac{7}{2}$ is:
Option 1: $101 \frac{1}{2}$
Option 2: $52 \frac{1}{2}$
Option 3: $28 \frac{1}{2}$
Option 4: $25 \frac{1}{4}$
Correct Answer: $52 \frac{1}{2}$
Solution : LCM of Fraction = $\frac{\text {LCM of numerator}}{\text{HCF of denominator}}$ LCM of 3, 5, and 7 = 3 × 5 × 7 = 105 HCF of 8, 16, and 2 = 2 So, LCM of $\frac{3}{8}, \frac{5}{16}$ and $\frac{7}{2}=\frac{105}{2}=52 \frac{1}{2}$ Hence, the correct answer
