Answer 1

$( \frac{1}{2} - \frac{3}{4} ) - ( \frac{5}{2} - \frac{5}{4} ) - ( \frac{3}{2} - \frac{3}{4} ) = \frac{2 - 3}{4} - \frac{10 - 5}{4} - \frac{6 - 3}{4} = - \frac{1}{4} - \frac{5}{4} - \frac{3}{4} = \frac{ - 1 - 5 - 3}{4} = - \frac{9}{4}$

Answer 2

ampllificam cu 2 la cele cu numitor 2[tex] (\frac{2}{4} - \frac{3}{4} ) - (\frac{10}{4} - \frac{5}{4} ) - (\frac{6}{4}- \frac{3}{4} ) = (-1-5-3)/4 = -9/4 [/tex]
