Question

2) The H.C.F of 12, 1.2, 12, .012 is -
A).12 B) 1.2 C) 0.12 D) None​

Answer 1

Answer:

So now,

1.2 can be written as 1.20

0.12 stays as 0.12

Next, you should convert both the numbers to whole numbers of the same ratio.

So 1.20 will be equal to 120

and 0.12 will be equal to 12

Now, find the HCF of 120 and 12.

HCF of 120 and 12 = 12

As we multiplied both 1.20 and 0.12 by 100, the HCF(which is now in whole number form) should be divided by 100.

12/100=0.12
