The LCM of $\frac{3}{8},\frac{5}{16}$ and $\frac{7}{2}$ is:
Answer & explanation
Correct answer: option 2
LCM of fraction = \(\frac{LCM\;of\;numerator}{HCF\; of\;denominator}\)
The given fractions are : $\frac{3}{8},\frac{5}{16}$ and $\frac{7}{2}$
LCM of 3, 5, 7 = 105
HCF of 8,16,2 = 2
The LCM of $\frac{3}{8},\frac{5}{16}$ and $\frac{7}{2}$ is = $52\frac{1}{2}$
