答案
(1)(40-5)÷5
=35÷5
=7,
7>6
所以(40-5)÷5>6;
(2)20×(6+4)
=20×10
=200,
20×6+4
=120+4
=124,
200>124
所以20×(6+4)>20×6+4;
(3)(24-18)×3
=6×3
=18,
18<20
所以(24-18)×3<20;
(4)360÷6÷12
=60÷12
=5,
360÷(6×12)
=360÷72
=5,
所以360÷6÷12=360÷(6×12);
(5)45-(21+41)
=45-62
=-17,
-17<20
所以<20;
(6)(82-24)÷2
=58÷2
=29;
82-24÷2
=82-12
=70,
29<70
所以(82-24)÷2<82-24÷2.
故答案为:>;>;<;=;<;<.
