Sagot :
a) A = 5 x 2 + 3.7
= 10 + 3.7
= 13.7
b) B= 4 x (9.2 + 2)
= 4 x 11.2
= 44.8
c) C= 17 - (4 x 3)
= 17 - 12
= 5
d) D= (1.9 + 3.11) / 11
= 5.01 / 11
= 0.4554545455
environ égal à 0.45
e) E= 7 x 9 + (12 - 4)
= 63 + 8
= 71
Voilà ! mais je ne suis pas sûre pour la d :)

bonsoir
A = (5x2) + 3.7 = 10 +3.7 = 13.7
B = 4 x (9.2 +7) = 4 x 16.2 = 64.8
C = 17 - (4x3) = 17-12 = 5
D = (1.9+3.11) : 11 = 5.01 : 11 = 0.455454545
E = (7x9) + (12-4) = 63 + 8 = 71
A = (5x2) + 3.7 = 10 +3.7 = 13.7
