Step-by-step explanation:

To add (or subtract) fractions, you need to have a common denominator.

So, our problem can be re-written as

To add (or subtract) fractions with common denominators, you keep the common denominator and add (or subtract) the numerator.

The last step is to see if our answer can be reduced.

A fraction can't be reduced if there is a prime number in either the numerator or the denominator.

There is a -1 in the numerator, which is prime, and therefore, the fraction can't be reduced.
