Question

решить дробный пример 13/18 - 1/24 - (29/72 + 6/36)

Answer 1

$\frac{13}{18} - \frac{1}{24} - ( \frac{29}{72} + \frac{6}{36} ) = \frac{1}{9} \\ \frac{29}{72} + \frac{6}{36} = \frac{29 + 12}{72} = \frac{41}{72} \\ \frac{13}{18} - \frac{1}{24} - \frac{41}{72} = \frac{52 - 3 - 41}{72} = \frac{8}{72} = \frac{1}{9}$
