34×(5+6)______34×5+6

120÷(5+3)______120÷5÷3

58+118+0______58×118×O

180÷6÷3______180÷(6÷3)

99×99+199______100×100.

答案

(1)96÷2÷6,

=48÷6,

=8;

96÷(6×2),

=96÷12,

=8;

8=8,所以96÷2÷=96÷(6×2);

(2)34×(5+6),

=34×11,

=374;

34×5+6,

=170+6,

=176;

374>176,所以34×(5+6)>34×5+6;

(3)120÷(5+3),

=120÷8,

=15;

120÷5÷3,

=24÷3,

=8;

15>8,所以120÷(5+3)>20÷5÷3;

(4)58+118+0=176;

8×118×O=0;

176>0,所以58+118+0>58×118×O;

(5)180÷6÷3,

=30÷3,

=10;

180÷(6÷3),

=180÷2,

=90;

10<90,所以180÷6÷3<180÷(6÷3);

(6)99×99+199,

=99×99+99+100,

=99×(99+1)+100,

=9900+100,

=10000;

100×100=10000,所以99×99+199=100×100.

故答案为:=,>,>,>,<,=.
