Explicație pas cu pas:

1)     712 : 7 = 101 rest 5;     564 : 6 = 94;     913 : 4 = 228 rest 1

643 : 8 = 80 rest 3;     603 : 9 = 67;     419 : 7 = 59 rest 6    708 : 3 = 236

420 : 5 = 84

______________________________________________________

2) a)   93 : 3 = 31 rest 0;   632 : 8 = 79 rest 0;    415 : 4 = 103 rest 3

605 : 3 = 201 rest 2;    914 : 9 = 101 rest 5;   863 : 7 = 123 rest 2

282 : 6 = 47 rest 0;    712 : 4 = 178 rest 0

___________________________________________________

b)

a : 9 = 45 rest 3

a = 45 × 9 + 3

a = 405 + 3

a = 408

Verific:   408 : 9 = 45 rest 3

_______________________

436 : b = 9 rest 4

b = ( 436 - 4 ) : 9 →  aplic teorema impartirii cu rest

b = 432 : 9

b = 48 ( impartitorul )

V:     436 : 48 = 9 rest 4

____________________

563 : b = 7 rest 3

b = ( 563 - 3 ) : 7

b = 560 : 7

b = 80

V:    563 : 80 = 7 rest 3

___________________

a : 4 = 152 rest 2

a = 152 × 4 + 2

a = 608 + 2

a = 610

V:    610 : 4 = 152 rest 2

______________________

486 : b = 5 rest 1

b = ( 486 - 1 ) : 5

b = 485 : 5

b = 97

V:      486 : 97 = 5 rest 1

_________________

936 : b = 4 rest 0

b = 936 : 4

b = 234

Verific:       936 : 234 = 4 rest 0

___________________________

a : 8 = 86 rest 2

a = 86 × 8 + 2

a = 688 + 2

a = 690  → deimpartitul

V:      690 : 8 = 86 rest 2

______________________

a : 9 = 135 rest 4

a = 135 × 9 + 4

a = 1 215 + 4

a = 1 219

Verific:   1 219 : 9 = 135 rest 4
