a)
[tex]2 \frac{1}{7} + \frac{3}{7} = 2 \frac{4}{7} [/tex]
b)
[tex]5 \frac{4}{9} + \frac{3}{9} = 5 \frac{7}{9} [/tex]
c)
[tex]1 \frac{5}{11} + 1 \frac{3}{11} = 2 \frac{8}{11} [/tex]
d)
[tex]1 \frac{3}{5} + 1 \frac{4}{5} = 2 \frac{7}{5} = 3 \frac{2}{5} [/tex]
e)
[tex]3 \frac{9}{15} + 2 \frac{11}{15} = 5 \frac{20}{15} = 6 \frac{5}{15} = 6 \frac{1}{3} [/tex]
f)
[tex]1 \frac{5}{6} + 1 \frac{5}{6} = 2 \frac{10}{6} = 3 \frac{4}{6} = 3 \frac{2}{3} [/tex]
g)
[tex]3 \frac{5}{8} + 7 \frac{5}{8} = 10 \frac{10}{8} = 11 \frac{2}{8} = 11 \frac{1}{4} [/tex]
h)
[tex]3 \frac{9}{14} + 11 \frac{11}{14} = 14 \frac{20}{14} = 15 \frac{6}{14} = 15 \frac{3}{7} [/tex]
Myślę że pomogłem ;)
