Seconde série – Correction Devoir N°25

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
