Question

how to add fractions

Answer 1

Find a common denominator and whatever you multiplied the denominator by, you multiply the numerator by, but if it has a common denominator, just add the numerator.

Answer 2

its simple. make sure that the denominators are the same and then you add the top numbers only and leave the denominator the same.
ex. 4+ 2= 
     8   6
   
6 can be turn into 8 by multiplying 2 4 6 8 
then you also have to multiply the top by the same number
