How To Find the HCF of 1.2 and 0.12?

Answer: The HCF of 1.2 and 0.12 is 0.12.

To find the Highest Common Factor (HCF) of two decimal numbers like 1.2 and 0.12, we need to convert them into whole numbers. We do this by multiplying both numbers by a power of 10 eliminating the decimal part.

For 1.2 and 0.12, multiplying by 100 would work since it moves the decimal two places to the right, making them whole numbers:

1.2 × 100 = 120

Now, we can find the HCF of 120 and 12. The HCF of these two numbers is the largest number that can evenly divide both of them. In this case, it’s 12.

Therefore, the HCF of 1.2 and 0.12 is 0.12 after converting them to whole numbers.
