As per the rule, remove the decimal from the numerator and put a 1 in the denominator. Now, the denominator of the fraction will have as many zeroes as there are number of digits in the decimal number.
Applying this rule,
Sice the leading zeroes does not make any sense, they can be dropped,
Simplify the fraction by cancelling out by 32 (HCF of 64 and 100000),
Thus, the required fraction is 2/3125 .
