Answer 1

Ответ:

$\frac{72}{80} - (x - \frac{12}{80} ) = \frac{15}{80} \\ - x + \frac{12}{80} = \frac{15}{80} - \frac{72}{80} \\ - x = - \frac{57}{80} - \frac{12}{80} \\ - x = - \frac{69}{80} \\ x = \frac{69}{80}$

$\frac{116}{125} - ( \frac{41}{125} - x) = \frac{94}{125} \\ - \frac{41}{125} + x = \frac{94}{125} - \frac{116}{125} \\ - \frac{41}{125} + x = - \frac{22}{125} \\ x = - \frac{22}{125} + \frac{41}{125} \\ x = \frac{19}{125}$
