exercice 10:
180+25% = 225€
19 600+ 12% = 21 952€
273 000 + 9% = 297 570€
exercice 11:
80 - 8x100 / 100 = 72 €
85-10x100/100 = 75kg
10-2x100/100 = 8H
à) 2x (10x100/100) = 20%
b) 1) 2 x (3x100/100) = 6%
3 x (3x100/100) = 9%
2) 250 000- (3x100/100) = 249 997 habs
3) 250 000 ÷2 = 125 000 hab
mais après je sais plus désolée
c)1) 50+ 10x 100/100 = 60 €
2) 60 - 10x100/100 = 50 €
d) 56 % - 20 % = 36 %
