⟹ 0.086

So it is clearly seen that after three decimal places the rational number is terminating

So the correct answer is C.

The product of two numbers is 1080. Their HCF is 30. Then their LCM is:

The decimal expansion of the number will be:

The least number by which multiplying to a rational number is obtained will be:

If for two rational numbers HCF = LCM, then the number must use:
