    7/8 + 1/2 = ?

    Find the common denominator

    A multiple of 2 is 8 which is the lowest common multiple of the two denominators

    You multiply the denominator by four to get 8 so you also multiply the numerator by four

    1/2 = 4/8

    Then add the numerators and the denominator stays the same

    7/8 + 4/8 = 11/8
