计算下面各题，能简算的要简算．1.25×7.6×80 96.5÷5÷0.2 32×0.25 19.8+0.16÷0.8 2.75×101-2.75 0.225÷0.25×4．

Answer 1

（1）1.25×7.6×80    
=（1.25×80）×7.6    
=100×7.6
=760

（2）96.5÷5÷0.2
=96.5÷（5×0.2）
=96.5÷1
=96.5

（3）32×0.25
=8×4×0.25
=8×（4×0.25）
=8×1
=8

（4）19.8+0.16÷0.8
=19.8+0.2
=20

（5）2.75×101-2.75    
=2.75×（101-1）
=2.75×100
=275

（6）0.225÷0.25×4
=0.225÷0.25×4
=0.9×4
=3.6
