a)
[tex]2 \frac{5}{6} - \frac{2}{3} = 2 \frac{5}{6} - \frac{4}{6} = 2 \frac{1}{6} [/tex]
b)
[tex]7 \frac{5}{8} - 1 \frac{1}{2} = 7 \frac{5}{8} - \frac{4}{8} = 7 \frac{1}{8} [/tex]
c)
[tex]3 \frac{4}{7} - 1 \frac{2}{5} = 3 \frac{20}{35} - 1 \frac{14}{35} = 2 \frac{6}{35} [/tex]
d)
[tex]2 \frac{7}{10} - 1 \frac{3}{25} = 2 \frac{175}{250} - 1 \frac{30}{250} = 1 \frac{150}{250} = 1 \frac{3}{5} [/tex]
Myślę że pomogłem ;)
