Question

Помогите пожалуйста решить

Answer 1

Решение ниже в приложении

$1 - \frac{5}{8} = \frac{8}{8} - \frac{5}{8} = \frac{3}{8}$

$3 \frac{3}{10} - 1 \frac{7}{15} = 3 \frac{9}{30} - 1 \frac{14}{30} = 2 \frac{39}{30} - 1 \frac{14}{30} = 1 \frac{25}{30} = 1 \frac{5}{6}$

$10 - 1\frac{1}{9} = 9 \frac{9}{9} - 1 \frac{1}{9} = 8 \frac{8}{9}$

$7 \frac{5}{18} - 1 \frac{7}{12} = 7 \frac{10}{36} - 1 \frac{21}{36} = 6 \frac{46}{36} - 1 \frac{21}{36} = 5 \frac{25}{36}$

$9 \frac{5}{6} - 2 \frac{3}{4} = 9 \frac{10}{12} - 2 \frac{9}{12} = 7 \frac{1}{12}$

$5 \frac{3}{24} - 1 \frac{1}{21} = 5 \frac{21}{168} - 1 \frac{8}{168} = 4 \frac{13}{168}$
