Here is a video tutorial https://www.YouTube.com/watch?v=HPetBqWKvZM on how to change an improper fraction to a mixed number.
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.
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
I wouldconvert both to improper fraction,find a common multiple (CM),calculate equivalent fraction with CM as the denominator,add the numerators,change the improper fraction to a mixed fraction, if required,simplify the fractional part of the mixed fraction - if appropriate and required.
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)

If its not an improper fraction then you cant....

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

You do the numerator divided by the denominator, then simplify the fractions if you can. (this is how you change a improper fraction to a mixed number, you cannot change a proper fraction to a mixed number)
