Odpowiedź:
2 6/8 - 5/8 = 2 1/8
1 6/7 - 4/7 = 1 2/7
7 3/5 - 4/5 = 6 4/5
5 6/9 - 8/9 = 4 7/9
A)
[tex]3 \frac{3}{8} - \frac{5}{8} = 2 \frac{11}{8} - \frac{5}{8} = 2 \frac{6}{8} = 2 \frac{3}{4} [/tex]
B)
[tex]2 \frac{3}{7} - \frac{4}{7} = 1 \frac{10}{7} - \frac{4}{7} = 1 \frac{6}{7} [/tex]
C)
[tex]8 \frac{2}{5} - \frac{4}{5} = 7 \frac{7}{5} - \frac{4}{5} = 6 \frac{3}{5} [/tex]
D)
[tex]6 \frac{5}{9} - \frac{8}{9} = 5 \frac{14}{9} - \frac{8}{9} = 5 \frac{6}{9} = 5 \frac{2}{3} [/tex]
