Răspuns:
a)
[tex] \frac{30}{13} [/tex]
b)
[tex] \frac{7}{3} [/tex]
c)
[tex] \frac{14}{5} [/tex]
Explicație pas cu pas:
a)
[tex] \frac{11}{13} + \frac{19}{13} = \frac{11 + 19}{13} = \frac{30}{13} [/tex]
b)
[tex] \frac{17}{15} + \frac{18}{15} = \frac{17 + 18}{15} = \frac{35}{15} = \frac{7}{3} [/tex]
c)
[tex] \frac{17}{10} + \frac{33}{30 } = \frac{17}{10} + \frac{11}{10} = \frac{17 + 11}{10} = \frac{28}{10} = \frac{14}{5} [/tex]
