Bonjour
[tex] = \frac{8}{3} \div \frac{6}{5} + \frac{6}{7} [/tex]
[tex] = \frac{8}{3} \times \frac{5}{6} + \frac{6}{7} [/tex]
[tex] = \frac{40}{18} + \frac{6}{7} [/tex]
[tex] = \frac{20}{9} + \frac{6}{7} [/tex]
[tex] = \frac{140}{63} + \frac{54}{63} [/tex]
[tex] = \frac{194}{63} [/tex]
Bonne soirée
