[tex]( \frac{9}{2} + \frac{5}{2} - \frac{1}{1} ) - ( \frac{1}{4} + \frac{3}{4} + \frac{5}{1} ) = \\ ( \frac{14}{2} - \frac{2}{2} ) - ( \frac{4}{4} + \frac{20}{4} ) = \\ \frac{12}{2} - \frac{24}{4} = \\ \frac{24}{4} - \frac{24}{4} = \\ 0[/tex]
= 0
Explicație pas cu pas:
(9/2 + 5/2 - 1) - (1/4 + 3/4 + 5)
= (9/2 + 5/2 - 2/2) - (1/4 + 3/4 + 20/4)
= (14/2 - 2/2) - (4/4 + 20/4)
= 12/2 - 24/4 = 6 - 6 = 0
