Answer 1

3.6×0.75×1.2）÷（1.5×24×0.18）
=（1.8×2×0.75×12÷10）÷（1.5×24×0.18）
=（1.8×1.5×12÷10）÷（1.5×24×0.18）
=0.5
26.44÷0.4+13.22+1.8
=13.22×2÷4×10+13.22+1.8
=13.22×5+13.22+1.8
=13.22×6+1.8
=79.32+1.8=81.12
26.39×36+26.39×83-263.9×1.9
=26.39×36+26.39×83-26.39×19
=26.39×（36+83-19）
=26.39×100
=2639
2.25×0.16+264×0.0225+52×2.25+0.225×2
=2.25×0.16+2.64×2.25+52×2.25+2.25×0.2
=2.25×（0.16+2.64+52+0.2）
=2.25×55
=2.25×50+2.25×5
=112.5+1.125
=123.75

Answer 2

（3.6×0.75×1.2）÷（1.5×24×0.18）=0.5
26.44÷0.4+13.22+1.8 =81.12
26.39×36+26.39×83-263.9×1.9=2639
2.25×0.16+264×0.0225+52×2.25+0.225×2=123.75

过程呢……要答案用计算器就可以了

Answer 3

（3.6×0.75×1.2）÷（1.5×24×0.18）=（3.6÷0.18）×（0.75÷1.5）×（1.2÷24）=0.5

26.44÷0.4+13.22+1.8=13.22×2÷0.4+13.22+1.8=13.22×（5+1）+6×0.3=6×（13.22+0.3）=81.12

26.39×36+26.39×83-263.9×1.9=26.39×36+26.39×83-26.39×19=26.39×（36+83-19）=2639

2.25×0.16+264×0.0225+52×2.25+0.225×2=2.25×0.16+2.64×2.25+52×2.25+2.25×0.2=
2.25×（0.16+2.64+52+0.2）=123.75
还算详细了吧？？

Answer 4

① (3.6×1.2×3/4)÷（3/2×2.4×1.8）=3/4×2/3=1/2
②13.22×(2×5/2+1)+0.3×6=13.52×6=81.12
③26.39×(83+36-19)=26.39×100=2639
④2.25×（0.16+2.64+52+0.2）=2.25×55=123.75

Answer 5

（3.6×0.75×1.2）÷（1.5×24×0.18）分子分母约分1.2与24约分,3.6与0.18约分,0.75与1.5约分=0.5
26.44÷0.4+13.22+1.8=66.1+13.22+1.8=66+13+1+0.1+0.22+0.8=81.12

26.39×36+26.39×83-263.9×1.9= 26.39×36+26.39×83-26.39×19=26.39*(36+83-19)=26.39*100=2639

2.25×0.16+264×0.0225+52×2.25+0.225×2=2.25×0.16+2.64×2.25+52×2.25+2.25×0.2
=2.25*(0.16+2.64+52+0.2)=2.25*55=123.75

Answer 6

1、（3.6×0.75×1.2）÷（1.5×24×0.18）
=20×0.5×0.05
=0.5
2、 26.44÷0.4+13.22+1.8
=66.1+13.22+1.8
=66+13.12+2
=68+12+1.12
=80+1.12
=81.12
3、 26.39×36+26.39×83-263.9×1.9
=36.39×（36+83-19）
=36.39×100
=3639
4、2.25×0.16+264×0.0225+52×2.25+0.225×2
=2.25×（0.16+2.64+52+0.2）
=2.25×55
=123.75
望采纳！！！
