4. 1/2 - 3/5 = 0,5 - 0,6 = -0,1
5. 7/20 - 3/5 = 0,35 - 0,6 = -0,25
1. 1/10 - 3/5 = 0,1 - 0,6 = -0,5
2. 1/15 - 3/5 = 1/15 - 9/15 = -8/15
1. 1/3 - 3/5 = 5/15 - 9/15 = -4/15
1. 3/7 - 3/5 = 15/35 - 21/35 = -6/35

2. 1/15 - 1/10 = 2/30 - 3/30 = -1/30
2. 1/2 - 2 3/5 = 1/2 - 13/5 = 0,5 - 2,6 = -2,1
4. 3/8 - 1 1/6 = 3/8 - 7/6 = 9/24 - 28/24 = -19/24
4. 1/4 - 2 2/3 = 1/4 - 8/3 = 3/12 - 32/12 = -29/12
5. 5/13 -3 1/2 = 5/13 - 7/2 = 10/26 - 91/26 = -81/26
5/7 - 1/4 = 20/28 - 7/28 = 13/28

chyba tak to powinno być;d
4.⁵/₁₀-²/₁₀=3/10
