96-27÷3______(96-27)÷3         105-(94-4)______ 105-(94+4)
答案

(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:<,=,>,>.
