Bonjour,
Calculer:
A= -2/21 x 14/5 - 8/5
A= (-2/3) x 2/5 - 8/5 simplifié 21 et 14 par 7
A= (-2x2)/(3x5) - 8/5
A= -4/15 - 8/5
A= (-4 - 8*3)/ 15
A= -28/15
B= 1/4+ 5/3x-1/5
B= 1/4 + (-5/(3x5))
B= 1/4 - 1/3 simplifié 5 e 5 reste -1/3
B= (1*3 - 1*4)/(4*3)
B= -1/12
C= (4/-3) + (-7/6)(-2/5)
C= -4/3 + (-7/3)(-1/5)
C= -4/3 + (7*1)/(3*x5)C= -4/3 + 7/15
C= (-4x5 + 7)/15
C= - 13/15
D= (8- 7*3)/ 15 x (-1*3+4x2)/18
C= - 13/15 * 5/18
C= (-13x5)/(15x18) simplifie 15 et 5
C= (-13 x 1)/(5x18)
C= -13/54
