what is 3/4+20=? what is 4/4+20=?

OpenStudy (anonymous):

3/4+20/1 find a common denominator, the common denominator is 4 so 20/1 x 4/4 is 80/4, so your answer is 83/4 which can't be simplified. 4/4+20/1, again common denominator is 4, so it's 4/4 + 80/4 which is 84/4 which can be simplified to 21, or you can just say 4/4=1 and 20+1 is 21.
