59 1/12 - 57 5/9
= 59 + 1/12 - (57 + 5/9)
First we need to put it all over a common denominator ( denominator = number on the bottom of the fraction)
59 + 1/12 - 57 - 5/9
= (59x12) + 1/12 - ( (57x9)/9 + 5/9)
= (708 + 1)/12 - ( (513 + 5)/9)
= 709/12 - 518/9
= (709x3)/(12x3) - (518x4)/(9x4)
= 2127/36 - 2072/36
= (2127 - 2072)/36
= 55/36 This is the final answer.
