How do you turn a decimal number into a fraction?

First, look at the place of the last digit. Using 0.35 as an example, the last digit (5) is in the hundredths place.

This number place, minus the -ths ending, becomes the number in the denominator. For the example, 100 would be the denominator (hundredths - ths = hundred = 100).

For the numerator, simply use the number behind the decimal point. In this case, 35. So your fraction would be 35/100. However, after you put it in fraction form, make sure you reduce the fraction as much as possible. Thus, 35/100 becomes 7/20 for the final answer.
