a)
[tex] \frac{9}{15} + \frac{4}{15} = \frac{13}{15} [/tex]
b)
[tex] \frac{7}{11} + \frac{2}{11} = \frac{9}{11} [/tex]
c)
[tex]4 \frac{3}{8} + 2 \frac{4}{8} = 6 \frac{7}{8} [/tex]
d)
[tex] \frac{3}{9} + \frac{7}{9} = \frac{10}{9} = 1 \frac{1}{9} [/tex]
e)
[tex]3 \frac{2}{3} + \frac{2}{3} = 3 \frac{4}{3} = 4 \frac{1}{3} [/tex]
f)
[tex]4 \frac{3}{5} + \frac{2}{5} = 4 \frac{5}{5} = 5[/tex]
g)
[tex]4 \frac{6}{7} + 2 \frac{1}{7} = 6 \frac{7}{7} = 7[/tex]
h)
[tex]3 \frac{5}{10} + 4 \frac{9}{10} = 7 \frac{14}{10} = 8 \frac{4}{10} = 8 \frac{2}{5} [/tex]
i)
[tex]2 \frac{4}{6} + 7 \frac{5}{6} = 9 \frac{9}{6} = 10 \frac{3}{6} = 10 \frac{1}{2} [/tex]
Myślę że pomogłem ;)
