Прошу решите, заранее спасибо.

Решите задачу:

$\frac{108}{109} - \frac{75}{109} - \frac{12}{109} = \frac{33 - 12}{109} = \frac{21}{109 }$

$\frac{14 + 154 - 64 - 54}{187} = \frac{50}{187}$

$\frac{(37 - 15) - (17 + 15)}{43} = \frac{22 - 32}{43} = \frac{ - 10}{43}$

$\frac{18 - (5 + (9 - 6))}{27 } = \frac{10}{27}$

$\frac{123 - 83 - 26}{147} = \frac{40 - 26}{147} = \frac{14}{147}$

$\frac{19 + 129 - 39 - 29}{134} = \frac{148 - 39 - 29}{134} = \frac{109 - 29}{134} = \frac{80}{134}$

$\frac{(24 - 12) - (14 - 12)}{39} = \frac{12 - 2}{39} = \frac{10}{39}$

$\frac{19 - (6 + (10 - 7))}{29} = \frac{10}{29}$
