    Find the least common denominator, which is 24 (7(3)-5(2)) / 24 (21-10) / 24 11/ 24

    Multiplying by 3/3 to the (7/8) yields (21/24)

    I thought the least common denominator would be 4 becuse 4 goes into 12 and 8

    Sure, Since we established that the LCD is 24, You have to make both of the fractions in the form where the denominator is 24 for both. For 7/8, to make it have the denominator 24, multiply 3/3 to it and you get: 21/24 For 5/12, to make the denominator 24, multiply 2/2 to it and you get: 10/24 Subtract both fractions together and youll get 11/24
