(1)40×8+2, =320+2, =322; 40×(8+2), =40×10, =400; 322<400,所以40×8+2<40×(8+2); (2)720÷24=30; 720÷6÷4, =120÷4, =30; 30=30,所以720÷24=720÷6÷4; (3)96-27÷3, =96-9, =87; (96-27)÷3, =69÷3, =23; 87>23,所以96-27÷3>(96-27)÷3; (4)105-(94-4), =105-90, =15; 105-(94+4), =105-98, =7; 15>7,所以105-(94-4)>105-(94+4). 故答案为:<,=,>,>. |
