  1. well first a typical common denominator example

    find a common denominator to compare

    1/3 and 2/5

    the denominator will have to have a 3 in it and a five in it
    In this simple case 3*5 = 15 will work
    Now find something over 15 that is the same as 1/3
    multiply top and bottom by five
    (1*5) /(3*5) = 5/15

    Now work on 2/5
    multiply top and bottom by 3
    (2*3) / (5*3) = 6/15

    Now if I wanted to add 1/3 + 2/5
    I could add their equivalents with the common denominator of 15
    1/3 + 2/5 = 5/15 + 6/15 = 11/15
