You divide the numerator and denominator of the fraction by their highest common factor. Alternatively, divide them by any commo factor and repeat that process until the common factor is 1.
A fraction is not an integer.
To solve a Dissimilar Fraction,you must change the denominator to a similar fraction then proceed with the Adding/Subtracting Dissimilar Fraction...
112 is an integer, not a fraction.
You cannot solve a fraction. You can solve a question about fractions, you can carry out basic operations with fractions, convert them from one form to another but none of these is "solving" them.
They are the fundamental operations of arithmetic: addition, subtraction, multiplication and division.
An integer is a fraction if, in its lowest terms, the denominator is 1.
There is no need to do so.

You solve the equation the same way as you would any other equation. Whether the variable is a fraction or otherwise will only become clear once you solve the equation. In other words, you don't initially KNOW whether the solution will be a fraction or not.
