Correct Answer: 0.9
Solution :
$0.15 = \frac{15}{100}$
$0.18 =\frac{18}{100}$
$0.45 =\frac{45}{100}$
We know, LCM of fractions = $\frac{\text{LCM of numerators}}{\text{HCF of denominators}}$
So, LCM of $ \frac{15}{100}, \frac{18}{100}$, and $\frac{45}{100}=\frac{90}{100}=0.9$
Hence the correct answer is 0.9.
