An example should help.
2 3/4 = 11/4
To convert from the mixed fraction (on the left) to the improper fraction (on the right), I multiplied 2 x 4, and added 3 to the result. (The reasoning here is that 2 can be converted to the denominator 4, 2 = 8/4. This can then be added to the existing 3/4.)
To convert from the improper fraction (on the right) to the mixed fraction (on the left), divide 11 by 4. The integer part (2) is the whole number; the remainder (3) is put over the denominator (4), to get 3/4. Reasoning: Similar as above; 11/4 can be separated into two parts, one of them a whole number: 11/4 = 8/4 + 3/4.
Some numbers are improper fractions and some are not. For example, 1/2 or 0.5 is a number but not an improper fraction. And there is no way in which you can express it as an improper fraction.
You change them into improper or topheavy fractions.
First you would want to change the mixed number to an improper fraction. Then you can subtract
you have to multiply the top and bottom number by the same number
Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly

twelve eighths is already in improper fraction, an improper fraction is a fraction which has a numerator (top number) larger than the denominator (bottom number)
You change them into improper or topheavy fractions.
If its not an improper fraction then you cant....

improper fraction
I don't think you can but, you can change an improper fraction to a decimal.
improper fraction

you have to multiply the top and bottom number by the same number
You change it into an improper fraction, then simplify it, then if you want to, change it back to a mixed number.
595/24 is an improper fraction; to change it to mixed number = 24 19/24
