Odpowiedź:
A)
[tex]1 \frac{2}{5} + \frac{1}{8} = 1 \frac{16}{40} + \frac{5}{40} = 1 \frac{21}{40 }[/tex]
B)
[tex]4 \frac{3}{5} + 2 \frac{2}{3} = 4 \frac{9}{15 } + 2 \frac{10}{15} = 7 \frac{4}{15} [/tex]
C)
[tex]5 \frac{3}{5} - 1 \frac{1}{4 } = 5 \frac{12}{20} - 1 \frac{5}{20} = 4 \frac{7}{20} [/tex]
D)
[tex]5 \frac{2}{5} - 3 \frac{7}{10} = 5 \frac{4}{10} - 3 \frac{7}{10} = 1 \frac{7}{10} [/tex]
