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.

If you know how to turn a mixed number into a fraction and a fraction into a decimal do that then make it negative.
divide the top number of the fraction by the bottom number to get your decimal. To turn that into a fraction, multiply by 100 and then add your % sign. e.g. 2/4---> 2 divided by 4 = 0.5 0.5 x 100= 50%
To change a whole number with a decimal into a fraction, you take the decimal and put it into a fraction in simplest form. Let me give you an example so you understand better: 13.678 = 13 678/1000 = 13 339/500. You change it to a mixed fraction.
you can change a fraction to a decimal by dividing the bottom number into the top number.
