666hello

$1) \ \ 5 \frac{1}{6} - 1 \frac{5}{6} = \frac{31}{6} - \frac{11}{6} = \\ \\ \frac{20}{6} = \frac{10}{3} .$

$2) \ \ 4 \frac{8}{15} - 3 \frac{7}{15} = \\ \\ (4 - 3) + ( \frac{8}{15} - \frac{7}{15} ) = 1 + \frac{1}{15} = \\ \\ \frac{16}{15} .$

$3) \ \ 2 \frac{17}{18} - 1 \frac{13}{18} = \\ \\ ( 2 - 1) + ( \frac{17}{18} - \frac{13}{18} ) = 1 + \frac{4}{18} = \\ \\ 1 + \frac{2}{9} = \frac{11}{9} .$

Ответ:

$5 \frac{5}{6} - 1 \frac{5}{6} = \frac{20}{6} = 3 \frac{1}{3 }$

$4 \frac{8}{15} - 3 \frac{7}{15} = 1 \frac{1}{15}$

$2 \frac{17}{18} - 1 \frac{13}{18} = 1 \frac{4}{18} = 1 \frac{2}{9}$
