a)
[tex] \frac{1}{4} + \frac{1}{2} = \frac{1}{4} + \frac{2}{4} = \frac{3}{4} [/tex]
b)
[tex] \frac{3}{4} + \frac{1}{8} = \frac{6}{8} + \frac{1}{8} = \frac{7}{8} [/tex]
c)
[tex] \frac{5}{8} + \frac{1}{4} = \frac{5}{8} + \frac{2}{8} = \frac{7}{8} [/tex]
d)
[tex] \frac{2}{3} + \frac{8}{12} = \frac{8}{12} + \frac{8}{12} = \frac{16}{12} = 1 \frac{4}{12} [/tex]
Myślę że pomogłem ;)
