Show answer & explanation
Correct answer: A
LCM of decimals: Make all numbers whole by multiplying by the same power of 10.
1.5, 3, and 0.6 become 15, 30, and 6 after multiplying by 10.
LCM(15, 30, 6) = 30.
Divide back by 10: 30 / 10 = 3.
The value 0.3 is the HCF of these decimal numbers, not the LCM.
Correct answer: 3.
