Step 2: Changing decimal into a fraction: Since there are 2 digits in 75, the very last digit is the "100th" decimal place. So we can just say that .75 is the same as 75/100, and since 75/100 isn't reduced, you need to find the GCF which is .25 and then you divide 75 and 100 by 25. and you will come out with 3/4.

Example: .75= seventy-five hundredths = 75/100 = 3/4
