Bonsoir ,
Exercice 1 :
A=213
B=327
C=109
D=604
E=718
F=745
G=0,019 (0,02)
H=804
Explications étape par étape:
A=24×9-3
=216-3
=213
B=123+51×4
=123+204
=327
C=104+45/9
=104+5
=109
D=902/2+51×3
=451+153
=604
E=62×9+32×5
=558+160
=718
F=800-(1+54)
=800-55
=745
G=(54/710)÷4
=(27/355)÷4
=27/(355×4)
=27/1420
H=(78+8×7)(24-2×9)
=(78+56)(24-18)
=134×6
=804
