4/9 + 8/9 = 12/9 = 4/3
8 + 9/4 = 10 1/4
9/8
8/9 + 4/7 = ((8*7)+(4*9))/(9*7) = 92/63
5/8 + 2/4 = 36/32 or 9/8 or 11/8
(1/4) + (7/8) = (2/8) + (7/8) = 9/8 = 11/8
4 / 5 + 8 / 9 = (9 * 4) / (9 * 5) + (5 * 8) / (5 * 9) = 36 / 45 + 40 / 45 = (36 + 40) / 45 = 76 / 45
5/9 + 4/12 = 96/108 or 8/9
9 + 4 + 7 + 8 = 28
9/16 + 2/8 9/16=9/16 2/8=4/16 9+4=13 so......13/16 is the answer!
6/27 + 8/36 = 4/9
It is: 16/9
