Answer 1

Răspuns:

1.(6×6+9×5):9=9

(36+45):9=9

81:9=9

(3×4+5)-(6×5-5×4)=7

(12+5)-(30-20)=7

17-10=7

56:(8×4-2×7-5×2)=7

56:(32-14-10)=7

56:8=7

8×10-(5×5+6×6)=19

8×10-(25+36)=19

8×10-61=19

80-61=19

2. 9×8-(64:8+42:6)<6×7+(10×10-6×3)=

9×8-(8+7)=72-15=57

6×7+(100-18)=42+82=124

57<124 (A)
