Sagot :
Bonjour !
Réponse :
[tex]c =-\frac{5}{3}[/tex]
[tex]d=\frac{32}{15}[/tex]
Explications étape par étape :
[tex]c=\left(\frac{4}{5}-\frac{11}{3}\right)\times \frac{25}{43}[/tex]
[tex]c=\frac{4\times3-5\times11}{5\times3}\times\frac{25}{43}[/tex]
[tex]c =-\frac{43}{15}\times \frac{25}{43}\\\\Nous\:\:supprimons\:\:les\:\:nombres\:\:43:\\\\c=-\frac{25}{15}\\\\Nous\:\:simplifions:\\\\c=-\frac{5}{3}[/tex]
[tex]d=\frac{2}{5}\div \frac{3}{15}+\frac{2}{15}\\\\d=\frac{2}{5}\times \frac{15}{3}+\frac{2}{15}\\\\d=2+\frac{2}{15}\\\\d=\frac{2\times \:15+2}{15}\\\\d=\frac{32}{15}[/tex]
Bonjour
c=(4/5-11/3) ×25/43
C = [(4 x 3) / (5 x 3) - (11 x 5) / (3 x 5)] x 25/43
C = (12/15 - 55/15) x 25/43
C = - 43/15 x 25/43
C = - 1 075/645
C = (215 x - 5) / (215 x 3)
C = - 5/3
d= 2/5:3/15+2/15
D = 2/5 x 15/3 + 2/15
D = 30/15 + 2/15
D = 32/15.
