Answer 1

Răspuns:

27:5 = 5 rest 2.

Proba: 5•5+2 = 25+2 = 27

29:6 = 4 rest 5

Proba: 4•6+5 = 24+5 = 29

75:9 = 8 rest 3

Proba: 8•9+3 = 72+3 = 75

28:5 = 5 rest 3

Proba: 5•5+3 = 25+3 = 28

15:2 = 7 rest 1

Proba: 7•2+1 = 14+1 = 15

42:5 = 8 rest 2

Proba: 8•5+2 = 40+2 = 42

33:6 = 5 rest 3

Proba: 5•6+3 = 30+3 = 33

58:7 = 8 rest 2

Proba: 8•7+2 = 56+2 = 58

26:4 = 6 rest 2

Proba: 6•4+2 = 24+2 = 26

35:8 = 4 rest 3
