Bonjour,

Résolution :

EXERCICE 21 : Consigne : Calculer.

$A = \frac { - 7 } { 3 } \times \frac { 5 } { 4 } \times \frac { - 1 } { 3 }$

$A=-\frac{7}{3}\times \left(\frac{5}{4}\right)\times \left(\frac{-1}{3}\right)$

$A=\frac{-7\times 5}{3\times 4}\times \left(\frac{-1}{3}\right)$

$A=\frac{-35}{12}\times \left(\frac{-1}{3}\right)$

$A=-\frac{35}{12}\times \left(\frac{-1}{3}\right)$

$A=-\frac{35}{12}\left(-\frac{1}{3}\right)$

$A=\frac{-35\left(-1\right)}{12\times 3}$

$A=\frac{35}{36}$

$B = \frac { 4 } { 3 } \times \frac { - 5 } { 7 } \times \frac { - 1 } { 3 } \times ( - 5 )$

$B=\frac{4}{3}\left(-\frac{5}{7}\right)\times \left(\frac{-1}{3}\right)\left(-5\right)$

$B=\frac{4\left(-5\right)}{3\times 7}\times \left(\frac{-1}{3}\right)\left(-5\right)$

$B=\frac{-20}{21}\times \left(\frac{-1}{3}\right)\left(-5\right)$

$B=-\frac{20}{21}\times \left(\frac{-1}{3}\right)\left(-5\right)$

$B=-\frac{20}{21}\left(-\frac{1}{3}\right)\left(-5\right)$

$B=\frac{-20\left(-1\right)}{21\times 3}\left(-5\right)$

$B=\frac{20}{63}\left(-5\right)$

$B=\frac{20\left(-5\right)}{63}$

$B=\frac{-100}{63}$

$B=-\frac{100}{63}$

Bonne journée, portes toi bien.
