Bonjour
Exercice 26
[tex]\frac{1}{4} + \frac{1}{6}[/tex]
[tex]\frac{3}{12} + \frac{2}{12}[/tex]
[tex]\frac{3+2}{12} = \frac{5}{12}[/tex]
[tex]\frac{3}{4} + \frac{5}{6}[/tex]
[tex]\frac{9}{12} + \frac{10}{12}[/tex]
[tex]\frac{9+10}{12} = \frac{19}{12}[/tex]
[tex]\frac{7}{4} - \frac{2}{6}[/tex]
[tex]\frac{21}{12} - \frac{4}{12}[/tex]
[tex]\frac{21-4}{12} = \frac{17}{12}[/tex]
[tex]\frac{-11}{4} + \frac{-7}{6}[/tex]
[tex]\frac{-33}{12} + \frac{-14}{12}[/tex]
[tex]\frac{-33-14}{12}[/tex] [tex]= \frac{-47}{12}[/tex]
[tex]\frac{1}{4} - \frac{1}{6}[/tex]
[tex]\frac{3}{12} - \frac{2}{12}[/tex]
[tex]\frac{3-2}{12} = \frac{1}{12}[/tex]
[tex]\frac{1}{4} + \frac{5}{6}[/tex]
[tex]\frac{3}{12} + \frac{10}{12}[/tex]
[tex]\frac{3+10}{12} = \frac{13}{12}[/tex]
