Answer 1

Răspuns:

Explicație pas cu pas:

D : 7 = C rest R

=》 Din T.Î.R. -》 R < Î

-》 R < 7 , R € { 0 , 1 , 2 , 3 , 4 , 5 , 6 }

☆ Caz 1 :

D : 7 = 0 rest 0

D = 0 • 7 + 0

D = 0 + 0

◇ D = 0

☆ Caz 2 :

D : 7 = 1 rest 1

D = 1 • 7 + 1

D = 7 + 1

◇ D = 8

☆ Caz 3 :

D : 7 = 2 rest 2

D = 2 • 7 + 2

D = 14 + 2

◇ D = 16

☆ Caz 4 :

D : 7 = 3 rest 3

D = 3 • 7 + 3

D = 21 + 3

◇ D = 24

☆ Caz 5 :

D : 7 = 4 rest 4

D = 4 • 7 + 4

D = 28 + 4

◇ D = 32

☆ Caz 6 :

D : 7 = 5 rest 5

D = 5 • 7 + 5

D = 35 + 5

◇ D = 40

☆ Caz 7 :

D : 7 = 6 rest 6

D = 6 • 7 + 6

D = 42 + 6

◇ D = 48
