填空题
96÷2÷6______96÷(6×2)
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:=,>,>,>,<,=.
