Réponse :

A= $\frac{9}{14}$

B= $\frac{1}{6}$

C= $\frac{2}{1}$ = 2

D= $\frac{23}{6}$

Détails des calculs :

A= $\frac{3}{7}$ × $\frac{14+5}{6}$ = $\frac{3}{7}$ × $\frac{19}{6}$ = $\frac{3*19}{7*6}$ = $\frac{57}{42}$ = $\frac{9}{14}$

B= $\frac{3*7}{7*3}$ - $\frac{5}{6}$ = $\frac{21}{21}$ - $\frac{5}{6}$ = $\frac{6}{6}$ - $\frac{5}{6}$ = $\frac{6-5}{6}$ = $\frac{1}{6}$

C= 12× ( $\frac{2}{6}$ - $\frac{1}{6}$ ) = 12× ( $\frac{2-1}{6}$ ) = 12× $\frac{1}{6}$ = $\frac{12}{6}$ = $\frac{2}{1}$ = 2

D= $\frac{12*1}{3}$ - $\frac{1}{6}$ = $\frac{12}{3}$ - $\frac{1}{6}$ = $\frac{24}{6}$ - $\frac{1}{6}$ = $\frac{24-1}{6}$ = $\frac{23}{6}$
