Question

b) Afla toate numerele care impartite la 9 dau catul 12.

Answer 1

Răspuns:

a : 9 = 12

a = 12 × 9

a = 108

a : 9 = 12 rest 1

a = 12 × 9 + 1

a = 108 + 1

a = 109

a : 9 = 12 rest 2

a = 12 × 9 + 2

a = 108 + 2

a = 110

a : 9 = 12 rest 3

a = 12 × 9 + 3

a = 108 + 3

a = 111

a : 9 = 12 rest 4

a = 12 × 9 + 4

a = 108 + 4

a = 112

a : 9 = 12 rest 5

a = 12 × 9 + 5

a = 108 + 5

a = 113

a : 9 = 12 rest 6

a = 12 × 9 + 6

a = 108 + 6

a = 114

a : 9 = 12 rest 7

a = 12 × 9 + 7

a = 108 + 7

a = 115

a : 9 = 12 rest 8

a = 12 × 9 + 8

a = 108 + 8

a = 116
