3)10 8/11-4 5/11
4)14 4/7-5
5)16 2/15-4 8/15
6)4 6/13+5 5/13
7)15 8/9+5 5/9

Answer 1

Ответ:

$8 - \frac{5}{12} = 7 \frac{7}{12} \\ 6 - 2 \frac{7}{9} = 3 \frac{2}{9} \\ 10 \frac{8}{11} - 4 \frac{5}{11} = 6 \frac{3}{11} \\ 14 \frac{4}{7} - 5 = 9 \frac{4}{7} \\ 16 \frac{2}{15} - 4 \frac{8}{15} = 11 \frac{9}{15} \\ 4 \frac{6}{13} + 5 \frac{5}{13} = 9 \frac{11}{13} \\ 15 \frac{8}{9} + 5 \frac{5}{9} = 21 \frac{4}{9}$
