Explicație pas cu pas:
1.
[tex]\frac{17}{16}+\frac{12}{13}+\frac{15}{16}+\frac{14}{13}[/tex]
[tex]\frac{17}{16}+\frac{15}{16}+\frac{12}{13}\frac{14}{13}[/tex] =
[tex]\frac{32}{16} + \frac{26}{13} = 2 + 2 = 4[/tex]
2.
[tex]\frac{8}{14}+\frac{5}{14}+\frac{1}{3}+\frac{1}{14}+\frac{2}{3}[/tex]
[tex]\frac{8}{14}+\frac{5}{14}\frac{1}{14}+\frac{2}{3}+\frac{1}{3}[/tex]
[tex]\frac{14}{14}+\frac{3}{3}[/tex] = 1 + 1 = 2
