Rules for Adding Fractions
 

• If there are any mixed numbers
  either add the whole numbers separately
  or convert them into improper fractions.
• Find a common denominator (lowest common multiple).
• Change the numerators in the same ratio as the denominators i.e. whatever you did to the bottom do the same to the top.
• Add the numerators.
• Keep the denominator the same.
• Convert to a mixed number if necessary.

It sounds complicated but with practice you will find you can do it easily!!!!
