Réponse :
2) 1000 x .a.. = 75 000 ⇔ a = 75 000/1000 = 75
3) 5 x .b.. = 3500 ⇔ b = 3500/5 = 700
....c x 10 000 = 6900 ⇔ c = 6900/10000 = 69/100 ⇔ c = 0.69
4) 57.4 x d = 5740 000 ⇔ d = 5740 000/57.4 = 100 000
5) ...e. x 0.087799 = 87.7996 ⇔ e = 87.7996/0.087799 = 1000
7) 543.1 x ...f... = 5.431 ⇔ f = 5.431/543.1 = 0.01
8) 0.1 x 235 = 23.5
