，有过程，希望对你有帮助!!!

0.4×125×25×0.8

=（0.4×25）×（125×0.8）

=10×100=1000

1.25×（8+10）

=1.25×8+1.25×10

=10+12.5=22.5

9123-（123+8.8）

=9123-123-8.8

=9000-8.8

=8991.2

1.24×8.3+8.3×1.76

=8.3×（1.24+1.76）

=8.3×3=24.9

9999×1001

=9999×（1000+1）

=9999×1000+9999×1

=10008999

14.8×6.3-6.3×6.5＋8.3×3.7

=（14.8-6.5）×6.3＋8.3×3.7

=8.3×6.3+8.3×3.7

=8.3×（6.3＋3.7）

=8.3×10

=83

1.24+0.78+8.76

=（1.24+8.76）+0.78

=10+0.78

=10.78

933-157-43

=933-（157+43）

=933-200 =733

4821-998

=4821-1000+2

=3823

32×125×25

=4×8×125×25

=（4×25）×（8×125）

=100×1000

=100000 9048÷26

=（2600+2600+2600+1248）÷26

=2600÷26+2600÷26+2600÷26+1248÷26

=100+100+100+48

=348

2881÷ 43

=（1290+1591）÷ 43

=1290÷43+1591÷43

=30+37 =67 3.2×42.3×3.75-12.5×0.423×16

=3.2×42.3×3.75-1.25×42.3×1.6

=42.3×(3.2×3.75-1.25×1.6)

=42.3×(4×0.8×3.75-1.25×4×0.4)

=42.3×(4×0.4×2×3.75-1.25×4×0.4)

=42.3×(4x0.4x7.5-1.25x4x0.4)

=42.3×[4×0.4×(7.5-1.25)]

=42.3×[4×0.4×6.25]

=42.3×(4×2.5)

=423

1.8+18÷1.5-0.5×0.3

=1.8+12-0.15

=13.8-0.15

=13.65

6.5×8+3.5×8-47

=52+28-47 =80-47 =33 (80-9.8)×5分之2-1.32

=70.2X2/5-1.32

=28.08-1.32

=26.76

8×7分之4÷[1÷(3.2-2.95)]

=8×4/7÷[1÷0.25]

=8×4/7÷4

=8/7

2700×（506－499）÷900

=2700×7÷900

=18900÷900

=21

33.02－（148.4－90.85）÷2.5

=33.02－57.55÷2.5

=33.02－23.02

=10

（1÷1－1）÷5.1

=（1－1）÷5.1

=0÷5.1

=0

18.1＋（3－0.299÷0.23）×1

=18.1＋1.7×1

=18.1＋1.7

=19.8 最后祝学习进步!!!
