Answer 1

Пошаговое объяснение:

$2 - ( \frac{13}{33} - \frac{5}{22} ) = 2 - \frac{13 \times 2 - 5 \times 3}{11 \times 3 \times 2} = 2 - \frac{26 - 15}{66} = 2 - \frac{11}{66} = 2 - \frac{1}{6} = 1 \frac{6}{6} - \frac{1}{6} = 1 \frac{5}{6}$

$6 \frac{3}{16} - (2 \frac{3}{8} + 3 \frac{5}{12} ) = 6 \frac{3}{16} - ( 2\frac{3 \times 3}{24} + 3 \frac{5 \times 2}{24} ) = 6 \frac{3}{16} - 5 \frac{19}{24} = 6 \frac{3 \times 3}{16 \times 3} - 5 \frac{19 \times 2}{24 \times 2} = 5 \frac{48 + 9}{48} - 5 \frac{38}{48} = \frac{19}{48}$

$8 \frac{1}{12} - 3 \frac{4}{15} - 1 \frac{7}{30} = 8 \frac{3}{60} - 3 \frac{4 \times 4}{60} - 1 \frac{7 \times 2}{60} = 7 \frac{63}{60} - 3 \frac{16}{60} - 1 \frac{14}{60} = 3 \frac{63 - 16 - 14}{60} = 3 \frac{33}{60} = 3 \frac{11}{20}$
