Odpowiedź:

[tex]1-\frac{7}{8}=\frac{8}{8}-\frac{7}{8}=\frac{1}{8}\\\\1-\frac{5}{7}=\frac{7}{7}-\frac{5}{7}=\frac{2}{7}\\\\2-\frac{6}{7}=1\frac{7}{7}-\frac{6}{7}=1\frac{1}{7}\\\\2-\frac{3}{5}=1\frac{5}{5}-\frac{3}{5}=1\frac{2}{5}\\\\3-\frac{5}{10}=3-\frac{1}{2}=2\frac{2}{2}-\frac{1}{2}=2\frac{1}{2}\\\\3-\frac{2}{11}=2\frac{11}{11}-\frac{2}{11}=2\frac{9}{11}[/tex]

Odpowiedź:

1 - 7/8 = 8/8 - 7/8 = 1/8

1 - 5/7 = 7/7 - 5/7 = 2/7

2 - 6/7 = 1 i 7/7 - 6/7 = 1 i 1/7

2 - 3/5 = 1 i 5/5 - 3/5 = 1 i 2/5

3 - 5/10 = 2 i 10/10 - 5/10 = 2 i 5/10 = 2 i 1/2

3 - 2/11 = 2 i 11/11 - 2/11 = 2 i 9/11
