Answer 1

1、=3.84÷（0.25×0.4×0.8）
=3.84÷（0.1×0.8）
=3.84÷0.8
=4.8
2、=25×100+25×0.4+25×0.2
=2500+10+5
=2515
3、=3.96×（0.46+0.54）
=3.96×1
=3.96
4、=（45.9-32.7）÷（8×0.125）
=13.2÷1
=13.2
采纳吧！累死了！

Answer 2

3.84÷(0.25×0.32)
=3.84÷(0.25×4×0.08)
=3.84÷0.08
=48
1.25×(100+0.8)
=1.25×100+1.25×0.8
=125+1
=126
3.96×0.46+0.54×3.96
=3.96×(0.46+0.54)
=3.96×1
=3.96
(45.9-32.7)÷8÷0.125
= (45.9-32.7)÷(8×0.125）
=13.2÷1
=13.2

Answer 3

1、原式=3.84÷0.32÷0.25
=12*0.25
=48
2、原式=1.25 X 100 + 1.25*0.8
=125+1
=126
3、原式=3.96 X (0.46+0.54)
=3.96 X 1
=3.96
4、原式=(45.96-32.7)÷(8*0.125)
=13.26*1
=13.26

Answer 4

追答

按顺序写的，有问题可以问我。忘采纳。

Answer 5

1、=3.84/0.32/0.25=12/0.25=12*4=48
2、=1.25*100+1.25*0.8=125+1=126
3、=3.96*（0.46+0.54）=3.96*1=3.96
4、=（45.9-32.7）/（8*0.125）=13.2/1=13.2
