How to add fractions?
Here are the general steps and rules for adding fractions:

Make sure the denominators are the same
To add fractions, the denominators must be the same. If they're not already the same, find a common denominator. 
Find a common denominator
Try to identify the least common multiple (LCM) of the denominators. The LCM is the smallest number that both denominators divide into evenly. Sometimes its not easy to find the LCM, in that case you can always multiply both denominators and use this result as common denominator. 
Adjust the fractions
Express each fraction with the common denominator by multiplying the numerator and denominator of each fraction by the same factor. This ensures that the fractions have the same denominator. 
Add the numerators
Once the fractions have the same denominator, add the numerators together and keep the common denominator unchanged. 
Simplify, if necessary
Simplify the resulting fraction by reducing it to its simplest form. Divide both the numerator and the denominator by their greatest common factor.
Here's the process in mathematical terms:
