7%2F8%2B11%2F12 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 8 and 12 is 24 (note: if you need help with finding the LCM, check out this solver)


Now we need to get each denominator to 24



%283%2F3%29%287%2F8%29%2B11%2F12 Multiply 7%2F8 by %283%2F3%29


21%2F24%2B11%2F12 Multiply 7%2F8 and %283%2F3%29 to get 21%2F24



21%2F24%2B%282%2F2%29%2811%2F12%29 Multiply 11%2F12 by %282%2F2%29


21%2F24%2B22%2F24 Multiply 11%2F12 and %282%2F2%29 to get 22%2F24



Since both fractions have a common denominator of 24, we can now combine the fractions


%2821%2B22%29%2F24 Combine the fractions


43%2F24 Add the numerators



So

7%2F8%2B11%2F12=43%2F24
