Answer 1

679:9=75 rest 4

75×9+4=675+4=679

456:7=65 rest 1

65×7+1=455+1=456

973:6=162 rest 1

162×6+1=972+1=973

478:8=59 rest 6

59×8+6=472+6=478

639:4=159 rest 3

159×4+3=636+3=639

Answer 2

679 : 9 = 75 rest 4

75 × 9 + 4 = 675 + 4 = 679 → proba

__________________________

456 : 7 = 65 rest 1

65 × 7 + 1 = 455 + 1 = 456 → proba

_________________________

973 : 6 = 162 rest 1

162 × 6 + 1 = 972 + 1 = 973 → proba

___________________________

478 : 8 = 59 rest 6

59 × 8 + 6 = 472 + 6 = 478 → proba

____________________________

639 : 4 = 159 rest 3

159 × 4 + 3 = 636 + 3 = 639 → proba
