Why do we make the number of decimal places equal (by adding zeroes) while calculating the LCM and HCF of decimals? I need to understand this because if I convert the decimals to fractions (without adding zeroes) and calculate the LCM of the fractions, the answers differ.
For eg: LCM of 1.2, 0.60, 0.144 is 3.6 if I make the number of decimal places equal and make them 1200, 600 and 144. But the LCM is 72 if I find the LCM of 12/10, 60/100 and 144/1000.
