[tex]a) \frac{7}{8} + \frac{5}{4} = \frac{7}{8} + \frac{10}{8} = \frac{17}{8} [/tex]
[tex]b) \frac{11}{6} - \frac{3}{2} = \frac{11}{6} - \frac{9}{6} = \frac{2}{6} = \frac{1}{3}[/tex]
[tex]c) \frac{3}{5} + \frac{3}{7} \\ [/tex]
nu se poate simplifica la un număr întreg.
[tex]d) \frac{5}{9} + \frac{5}{6} = \frac{10}{18} + \frac{15}{18} = \frac{25}{18} [/tex]
[tex]e) \frac{7}{12} - \frac{3}{8} = \frac{7}{12} - \frac{9}{24} = \frac{14}{24} - \frac{9}{24} = \frac{5}{24} [/tex]
[tex]a) \frac{5}{3} + \frac{8}{9} = \frac{15}{9} + \frac{8}{9} = \frac{23}{9} [/tex]
[tex]
b) \frac{8}{5} - \frac{13}{10} = \frac{16}{10} - \frac{13}{10} = \frac{3}{10} [/tex]
c. nu se poate simplifica la un număr întreg.
[tex]d) \frac{7}{18} + \frac{5}{12} = \frac{14}{36} + \frac{15}{36} = \frac{29}{36} [/tex]
[tex]e) \frac{5}{8} - \frac{5}{10} = \frac{25}{40} - \frac{20}{40} = \frac{5}{40} = \frac{1}{8} [/tex]
3. nu-mi mai da timp sa scriu ❤️
