Let's say you have a decimal number that has a 0 at the left of the decimal point, (like 0.057), and you want to change it into a fraction. First take all the numbers to right of the decimal point (in this case 57, you can drop the leading 0's) and that will be your numerator (the "top" part of your fraction). For the denominator ("bottom" part) of your fraction, use a 1 followed by the same number of 0's as their are digits after the decimal point (in this case 3 -- here you must count the leading 0!). So 0.057 would be 57/1000 as a fraction.
Decimal numbers that have numbers other than 0 the the left of the decimal point can be converted into mixed numbers. Just use the numbers the the left for the integer part of the number, and the same procedure as above to convert to a fraction part. Best explained as an example: 2305.0994 is the same as 2305 994/10000.

How do you change proper fractions to mixed numbers?
do you mean from a fraction to a decimal? improper fractions can be changed into mixed numbers... 40/11 = 3 7/11 but proper fractions can only be changed to decimals... 11/40 = .275 this is because the proper fraction has no whole number value. the numerator is smaller than the denominator causing it to always be less than "1" so when dividing there is only a percentage of "1" and not a whole number with a remainder.
