Calculate the LCM of $\frac{72}{250}, \frac{126}{75}$ and $\frac{162}{165}$.
756/5
10/11
130/25
120/125
Here, $\frac{72}{250}=\frac{36}{125}, \frac{126}{75}=\frac{42}{25}$ and $\frac{162}{165}=\frac{54}{55}$
According to the formula,
Required LCM $=\frac{L C M \text { of } 36,42 \text { and } 54}{H C F \text { of } 125,25 \text { and } 55}=\frac{756}{5}=151 \frac{1}{5}$
