Question

ajutor va rog !......

Answer 1

c = 1  r = 2

a : 9 = 1 rest 2

a = 9 x1 + 2

a = 9 + 2

a = 11

c = 2 , r = 3

a : 9 = 2 rest 3

a = 9 x2 + 3

a = 18 + 3

a = 21

c = 3  , r = 4

a : 9 = 3 trest 4

a = 9 x 3 + 4

a = 27 + 4

a = 31

c = 4 , r = 5

a : 9 = 4 rest 5

a = 9 x4 + 5

a = 36 + 5

a = 41

c = 5  r= 6

a : 9 = 5 rest 6

a = 9 x5 + 6

a = 45 + 6

a = 51

c = 6 , r = 7

a: 9 = 6 rest 7

a = 9 x6 + 7

a = 54 + 7

a = 61

c = 7 , r = 8

a : 9 = 7 rest 8

a = 9 x7 + 8

a = 63 + 8

a = 71
