Subtract the denominator from the numerator. However many times you can do that without going into the negatives is your whole number. The number left after that is the new numerator.
For example, 10/7. 10-7=3. 10/7 = 1 3/7.
7.7 as a mixed number is 7 7/10. As an improper fraction it is 77/10. It is in simplest form.
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.

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....
You change them into improper or topheavy fractions.
An improper fraction has a numerator equal to or greater than the denominator. A mixed number is a combination of a whole number and a proper fraction. I'm not sure what a mixed improper fraction is. Whatever. To reduce any kind of fraction to its simplest form, find the GCF of the numerator and denominator. If the GCF is 1, the fraction is already in its simplest form. If not, divide the numerator and the denominator by the GCF. The result will be the simplest form.
