Question

Can you find the HCF of 1.2and 0.12

Answer 1

Answer:

Step-by-step explanation:

Let’s take two fractions (a/b) and (c/d).

To find LCM and HCF of (a/b) and (c/d) the generalized formula will be:

H.C.F = H.C.F of numerators / L.C.M of denominators

L.C.M = L.C.M of numerators / H.C.F of denominators

so,HCF of (1.2 , 0.12) =HCF of (12/10 , 12/100)=HCF of (12, 12) /LCM of (10, 100)

since=>HCF of (12 , 12) = 12 and LCM of (10 , 100) = 100

so, HCF of (1.2 , 0.12) =12/100 =0.12

Answer 2

Answer:

While finding the HCF for decimals, the first step would be to convert both the numbers into like decimals.(That is both the numbers should have equal number of digits after the decimal point).

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=0.12

The HCF of 1.2 and 0.12 = 0.12
