# Find the smallest

We know that if the denominator is in the form of , then we get terminating decimal digit, and it depends on the value of m or n. If we have m>n, then decimal digit terminates after m or if we have n > m, then digit terminates after n.

And, here we have Our numerator must be 7, so we cancel out 7 from the denominator to get terminating decimal digits.

And,

as we know 5 > 2, and 52 > 22. So, to place 52 in denominator we get a smaller rational number in comparison to place 22.

Our smallest rational number by which should be multiplied, so that its decimal expansion terminates after two places of decimal Rate this question :
