Bonjour,
[tex] \frac{1}{2} + ( \frac{ - 4}{ - 3} ) \times \frac{2}{4} [/tex]
[tex] = \frac{1}{2} + \frac{4}{3 } \times \frac{1}{2} [/tex]
[tex] = \frac{1}{2} + \frac{4}{6} [/tex]
[tex] = \frac{1 \times 3}{3 \times 2} + \frac{4}{6} [/tex]
[tex] = \frac{3}{6} + \frac{4}{6} [/tex]
[tex] = \boxed{ \frac{7}{6} }[/tex]
