1%2F12%2B1%2F15 Start with the given expression




In order to add these two fractions, these fractions need to have a common denominator.


In order to do that, we simply find that the LCM of 12 and 15 is 60 (note: if you need help with finding the LCM, check out this solver)


Now we need to get each denominator to 60



%285%2F5%29%281%2F12%29%2B1%2F15 Multiply 1%2F12 by %285%2F5%29


5%2F60%2B1%2F15 Multiply 1%2F12 and %285%2F5%29 to get 5%2F60



5%2F60%2B%284%2F4%29%281%2F15%29 Multiply 1%2F15 by %284%2F4%29


5%2F60%2B4%2F60 Multiply 1%2F15 and %284%2F4%29 to get 4%2F60



Since both fractions have a common denominator of 60, we can now combine the fractions


%285%2B4%29%2F60 Combine the fractions


9%2F60 Add the numerators



So

1%2F12%2B1%2F15=9%2F60



If want to reduce the fraction, 9%2F60 reduces to 3%2F20 (note: click here if you need help with reducing fractions)
