Exercice 1
82 – 15 = 67
40 : 8 = 5
94 – 15 = 79
10 × 7 = 70
91 – 54 = 37
3 × 11 = 33
21 : 7 = 3
66 – 41 = 25
14 + 65 = 79
9 : 3 = 3
6 : 3 = 2
74 – 45 = 29
95 – 47 = 48
63 + 98 = 161
20 : 10 = 2
9 × 8 = 72
5 × 6 = 30
99 – 36 = 63
49 + 84 = 133
62 + 35 = 97
Exercice 2
8 kg + 5 hg + 2 dag= 8520 g
6 kg + 3 hg + 2 g = 6302 g
6000 g + 300 + 2
5 kg + 3 kg + 250 g + 750 g = 9 kg
3,25 km + 750 m = 4 km
3600 m + 4 hm = 4 km
2 kg – 5 g = 1,995 kg
3 dal + 25 l + 75 l = 1,3 hl
6.25 m + 75 cm = 7 m
4,875 kg – 5 hg = 4,375 kg
9.9 hm + 10 m = 1km
