[tex]13\frac{2}{7}+5\frac{3}{10}=13\frac{20}{70}+5\frac{21}{70}=18\frac{41}{70}\\\\8\frac{3}{16}-3\frac{3}{4}=8\frac{3}{16}-3\frac{12}{16}=7\frac{19}{16}-3\frac{12}{16}=4\frac{7}{16}\\\\10-4\frac{2}{15}=9\frac{15}{15}-4\frac{2}{15}=5\frac{13}{15}[/tex]

Odpowiedź:

13 i 2/7 + 5 i 3/10 = 13 i 20/70 + 5 i 21/70 = 18 i 41/70

8 i 3/16 - 2 i 3/4 = 8 i 3/16 - 2 i 12/16 = 7 i 19/16 - 2 i 12/16 = 5 i 7/16

10 - 4 i 2/15 = 9 i 15/15 - 4 i 2/15 = 5 i 13/15
