Since 18 is the whole number in the given decimal, I put 18 as a whole number of the fraction and I take the decimal numbers as a numerator, meanwhile I take 1,000 as the denominator because the last decimal digit of the given decimal is in thousandths place.
The whole number of the given decimal is 105, so similar to the number 1, I put 105 as whole number and take the decimal numbers as the numerator, but unlike in the number 1 its denominator is not gonna be 1,000, it's because the last decimal digit is in ten thousandths places, so the denominator would be 10,000.
But if you're confused why my final answer is not same as i told, it's because i reduce my answer to its lowest term. To reduce a fraction to its lowest term find the Greatest Common Factor or GCF of the both denominator and numerator, and once you find the GCF, divide both numerator and denominator by their GCF, and if there is a whole number just copy it. In this case, 25 is the GCF of 325 and 10,000.
