Question

Помогите ребята только скорей и подробно

Answer 1

Ответ:

а)

$2 \frac{5}{6} - (1 \frac{5}{9} + \frac{1}{4} = \frac{17}{6} - ( \frac{14}{9} + \frac{1}{4} ) = \frac{17}{6} - \frac{65}{36} = \frac{37}{36}$

б)

$\frac{7}{20} - (3 \frac{5}{8} - 3 \frac{2}{5} ) = \frac{7}{20} - ( \frac{29}{8} - \frac{17}{5} ) = \frac{7}{20} - \frac{9}{40} = \frac{1}{8}$

в)

$\frac{3}{4} - ( \frac{4}{25} + \frac{7}{20} ) = \frac{3}{4} - \frac{51}{100} = \frac{6}{25}$

г)

$\frac{1}{2} - \frac{4}{45} + \frac{13}{15} = \frac{45 - 8 + 78}{90} = \frac{115}{90} = \frac{23}{18}$

д)

$\frac{14}{15} + \frac{11}{12} - 1 \frac{7}{10} = \frac{14}{15} + \frac{11}{12} - \frac{17}{10} = \frac{3} {20}$
