a)46:2 b)84:4 c)63:3 d)64:2
49:2 87:4 68:3 97:3
41:2 83:4 61:3 82:4

Aflati jumatatea si dublul fiecarui dintre numerele 64, 42, 88, 26.

Answer 1

a. 46:2=23
proba 23x2=46

b.84:4=21
proba 21x4=84

c. 63:3=21
proba 21x3=63

d. 64:2=32
proba 32x2=64

49:2=24 rest 1
proba 24x2+1=48+1=49

87:4=21 rest 3
proba 21x4+3=84+3=87

68:3=22 rest 2
proba 22x3+2=66+2=68

97:3=32 rest 1
32x3+1=96+1=97

41:2=20 rest 1
proba 20x2+1=40+1=41

83:4=20 rest 3
20x4+3=80+3=83

61:3=20 rest 1
proba 20x3+1=60+1=61

82:4=20 rest 2
proba 20x4+2=80+2=82

jumatatea si dublul lui:
- 64;
64:2=32
64x2=128

- 42;
42:2=21
42x2=84

- 88;
88:2=44
88x2=176

- 26;
26:2=13
26x2=52
