Question

помогите пожалуйста номер 220 срочно пожалуйста.

Answer 1

Переводим смешанные дроби в неправильные:

1) $\frac{41}{9} - 2 = \frac{41}{9} - \frac{18}{9} = \frac{23}{9} = 2\frac{5}{9}$

$\frac{19}{5} - 1 = \frac{19}{5} - \frac{5}{5} = \frac{14}{5} = 2,8$

$\frac{85}{12} - 6 = \frac{85}{12} - \frac{72}{12} = \frac{13}{12} = 1\frac{1}{12}$

2) $\frac{23}{3} - \frac{10}{3} = \frac{13}{3} = 4\frac{1}{3}$

$\frac{63}{11} - \frac{61}{11} = \frac{2}{11}$

$\frac{73}{15} - \frac{56}{15} = \frac{17}{15} = 2\frac{2}{15}$

3) $\frac{27}{10} - \frac{4}{5} = \frac{27}{10} - \frac{8}{10} = \frac{19}{10} = 1,9$

$\frac{97}{15} - \frac{1}{3} = \frac{97}{15} - \frac{5}{15} = \frac{92}{15} = 6\frac{2}{15}$

$\frac{107}{12} - \frac{1}{2} = \frac{107}{12} - \frac{6}{12} = \frac{101}{12} = 8\frac{5}{12}$

4) $\frac{11}{2} - \frac{9}{4} = \frac{22}{4} - \frac{9}{4} = \frac{13}{4} = 3\frac{1}{4} = 3,25$

$\frac{23}{6} - \frac{8}{3} = \frac{23}{6} - \frac{16}{6} = \frac{7}{6} = 1\frac{1}{6}$

$\frac{9}{5} - \frac{11}{10} = \frac{18}{10} - \frac{11}{10} = \frac{7}{10}$
