Question

The HCF of 1.2 and 0.12 is 

A) 1.2 

B) 12 

C) 0.12 

D) 120

Answer 1

We can write 1.2 as 12/10 = 120/100

1.2 = 120/100​,    0.12 = 12/​100

HCF of the numerators 120 and 12 is 12.

HCF of denominators 100 and 100 is also 100.

So, HCF of 120/100 and 12/100 is 12/100 i.e., 0.12.

∴ HCF of 1.2 and 0.12 is 0.12.

Hence the correct option is (c) 0.12

Answer 2

Correct option is C) 0.12
