What is the LCM of 3.6, 0.009, 0.27 ?

  1. A. 5.4
  2. B. 10.8
  3. C. 16.2
  4. D. 21.6

Correct Answer: B. 10.8

Explanation

Convert the decimals to fractions: 3600/1000, 9/1000, and 270/1000. The LCM of fractions is (LCM of numerators) / (HCF of denominators). LCM(3600, 9, 270) = 10800. HCF(1000, 1000, 1000) = 1000. So, LCM is 10800 / 1000 = 10.8.
