5 6/7 + 7 8/13

First: Least Common Denominator(LCD)= 91: multiplying

6/7 MULTIPLY 13/13- 6 MULTIPLY 13 = 78, 7 MULTIPLY 13 = 91
8/13 MULTIPLY 7/7- 8 MULTIPLY 6 = 48, 13 MULTIPLY 7 = 91
78/91 + 48/91 = 126/91, Denominator will always stay the same when adding.

Second: Simplfying
126/91 DIVIDE by 7/7 = 18/13
13 Goes into 18 once = 1 5/13

Third(LAST): Adding in the whole numbers
5+7+1 = 13 + 5/13 = 13 5/13
