1) 1/3 + 2/5 = (1×5)/(3×5) + (2×3)/(5×3) = 5/15 + 6/15 = 11/15
2) 1/2 - 1/3 = (1×3)/(2×3) - (1×2)/(3×2) = 3/6 - 2/6 = 1/6
3) 1/4 + 1/3 = 3/12 + 4/12 = 7/12
4) 1/4 - 1/5 = 5/20 - 4/20 = 1/20
5) 2/3 - 1/4 = 8/12 - 3/12 = 5/12
6) 2/3 + 2/9 = 6/9 + 2/9 = 8/9
7) 1/3 + 2/5 = 5/15 + 6/15 = 11/15
8) 7/8 - 1/2 = 7/8 - 4/8 = 3/8
9) 4/5 - 1/2 = 8/10 - 5/10 = 3/10
10) 1/8 + 2/3 = 3/24 + 16/24 = 19/24
11) 9/10 - 4/5 = 9/10 - 8/10 = 1/10
12) 2/7 + 1/4 = 8/28 + 7/28 = 15/28
13) 2/3 - 3/5 = 10/15 - 9/15 = 1/15
14) 1/5 + 2/7 = 7/35 + 10/35 = 17/35
15) 1/6 + 5/12 = 2/12 + 5/12 = 7/12
16) 4/5 - 1/9 = 36/45 - 5/45 = 31/45
17) 3/4 + 1/5 = 15/20 + 4/20 = 19/20
18) 5/8 - 2/5 = 25/40 - 16/40 = 9/40
