Răspuns:
a) [tex]\frac{17}{41} + \frac{8}{41} = \frac{17 + 8}{41} = \frac{25}{41}[/tex]
b) [tex]\frac{11}{25} + \frac{3}{50} = \frac{22}{50} + \frac{3}{50} = \frac{22 + 3}{50} = \frac{25}{50} = \frac{1}{2}[/tex]
c) [tex]\frac{7}{12} + \frac{5}{18} = \frac{21}{36} + \frac{10}{36} = \frac{21 + 10}{36} = \frac{31}{36}[/tex]
