Find the HCF and LCM of 1.5, 3 and 0.6   

A) 3

B)  4

C)  5

D)  6

Correct Answer: A

Solution :

Making the same number of decimal places, given numbers become 1.5, 3.0 and 0.6. Number of decimal places in each = 1. Without decimal places, these numbers are 15, 30, 1 HCF of 15, 30, 6 = 3 \[\therefore \] HCF of given numbers = 0.3 LCM of 15, 30, 6 \[=(3\times 2\times 5)=30,\] i.e., 3 \[\therefore \] LCM of given numbers = 3.0,
