Cine a calculat corect? Efectuează proba împărţirilor urmatoa 98:12 8 rest 10 63:4=15 rest 3 29:12= 2rest 9​

Răspuns :

Rezolvare:

98 : 12 = 8 rest 10

Proba 12 × 8 + 10 = 96 + 10 = 106 → incorect

Corect 12 × 8 + 2 = 96 + 2 = 98

***

63 : 4 = 15 rest 3

Proba 4 × 15 + 3 = 60 + 3 = 63corect!

***

29 : 12 = 2 rest 9

proba 12 × 2 + 9 = 24 + 9 = 33 → incorect

Corect 12 × 2 + 5 = 24 + 5 = [tex]29[/tex]

[tex]\bf 98:12=8\ rest\ 10 \Leftrightarrow 98=12\cdot8+10 \Leftrightarrow98=106\ \ (F)[/tex]

[tex]\bf 63:4=15\ rest 3 \Leftrightarrow 63 = 15\cdot4+3 \Leftrightarrow63=63 \ \ (A)[/tex]
