find a common denominator first

OpenStudy (anonymous):

after you find the common denominator, figure out what you need to multiply each denominator by to get the common denominator

i would mulitple -11 by 4 and get 44

OpenStudy (smurfy14):

common denom is 44 so it turns into -20/44 + 11/44 which gives you -9/44
