Explications étape par étape
Bonjour,
La prochaine fois, ne t'y prends pas à la dernière minute pour faire tes exercices...
24 / ... = -8
... = 24/-8 = -3
24 / (-3) = -8
-24 / ... = -12
... = -24/-12 = 2
-24 / 2 = -12
-18 / ... = -6
... = -18/-6
... = 3
-18 / 3 = -6
25 / ... = -5
... = 25/-5 = -5
25 / -5 = -5
-42 / ... = 6
... = -42/6 = -7
-42 / -7 = 6
-16 / ... = 32
... = -16/32 = -1/2
-16 / (-1/2) = 32
... / 2.5 = -100
... = -100 x 2.5 = -250
-250 / 2.5 = 100
... / 2.5 = -5
... = -5 x 2.5 = -12.5
-12.5 / 2.5 = -5
... / 5 = 100
... = 100 x 5 = 500
500 / 5 = 100
... / (-1) = 100
... = 100 x (-1) = -100
-100 / (-1) = 100
... / (-20) = -80
... = -80 x -20 = 1600
1600 / (-20) = -80
... / (-7) = 35
... = 35 x (-7) = -245
-245 / (-7) = 35
Exercice 7 :
A = 3.5 / (-4 x 8 + 25)
A = 3.5 / (-32 + 25)
A = 3.5 / (-7)
A = -1/2
B = (8 - 10) x (-3) + 3
B = (-2) x (-3) + 3
B = 6 + 3
B = 9
