Réponse :

a = b/c

b = a x b

a/ 6 = 12/2

b/ 7= 14/2

c/ 10 = 20/2

d/ 15 = 30/2

e/ 6 = 18/3

f/ 7 = 21/3

g/ 10 = 30/3

h/ 15 = 45/3

i/ 6 = 42/7

j/ 7 = 49/7

k/ 10 = 70/7

l/ 15 = 105/7

Q= quotien            R= reste

a/ 415 ÷7

Q =  59                     R = 2

b/ 415 ÷59

Q =  7                     R = 2

c/ 3192 ÷56

Q =  57                    R = 0

d/3192 ÷ 57

Q =  56                     R = 0

voila :)
