Example Question #96 : Decimals And Percentage

Convert  into a fraction in lowest terms.

Possible Answers:

Correct answer:

Explanation:

Since this percentage includes a decimal already, this question requires changing the percentage to a decimal first. One way to do it is to divide the number by 100 (note that this is the same thing as turning the number into a fraction over 100).

Now, it helps if you know decimal place values. To turn this into a fraction, put 9925 over the place value of the furthest right digit, in this case the 5. This is the ten thousandths place so put 9925 over 10000

Now reduce it to lowest terms by dividing the numerator and denominator evenly by the same number. I can see that 25 is a common factor so I will try that first.

Since no number will go into both 397 and 400, this is the answer reduced to lowest terms.
