Question

（2014•桐梓县模拟）计算下面各题，能简算的要简算：

[800×（1+(1)/(4)）-360]×2.5	7200÷25÷4	46.5×43.5+4.35×285-25×43.5
5.25×(11)/(12)+(11)/(12)×(3)/(4)	(5)/(6)×(1)/(15)÷(7)/(18)	[3.75-（0.2+(1)/(3)）×4.5]÷13.5．

Answer 1

（1）[800×（1+(1)/(4)）-360]×2.5
=[800×1(1)/(4)-360]×2.5
=[1000-360]×2.5
=640×2.5
=1600；

（2）7200÷25÷4
=7200÷（25×4）
=7200÷100
=72；

（3）46.5×43.5+4.35×285-25×43.5
=46.5×43.5+43.5×28.5-25×43.5
=（46.5+28.5-25）×43.5
=50×43.5
=2175；

（4）5.25×(11)/(12)+(11)/(12)×(3)/(4)
=（5.25+(3)/(4)）×(11)/(12)
=6×(11)/(12)
=(11)/(2)；

（5）(5)/(6)×(1)/(15)÷(7)/(18)
=(1)/(18)÷(7)/(18)
=(1)/(7)；

（6）[3.75-（0.2+(1)/(3)）×4.5]÷13.5
=[3.75-(8)/(15)×4.5]÷13.5
=[3.75-2.4]÷13.5
=1.35÷13.5
=0.1．
