Answer 1

12.5-6.5÷2.5简算

12.5-6.5÷2.5的差是（9.9）
12.5-6.5÷2.5
=12.5-2.6
=9.9

（12.5+12.5＊7）＊2.5＊0.4简算

12.5*(7+1)*(2.5*0.4)

2.5*96*12.5 简算

这道题这样算，
算式2.5×4×3×8×12.5=10×3×100，
所以结果是3000。

4800*12.5*2.5*3.2简算

4800x12.5x8x2.5x0.4
=4800x100x1
=480000

简算1800÷12.5÷2.5÷3.2

1800÷12.5÷2.5÷3.2
=1800÷(12.5x2.5x3.2)
=1800÷((12.5x0.8)x(2.5x4))
=1800÷(10x10)
=1800÷100
=18

4800÷12.5÷2.5÷3.2 简算

原式
=4800/（12.5*8）/（2.5*0.4）
=4800/100/1
=48

2.5*(8-0.4)*12.5简算

2.5*(8-0.4)*12.5
=2.5*12.5*(8-0.4)
=2.5*12.5*8-2.5*12.5*0.4
=2.5*(12.5*8)-(2.5*0.4)*12.5
=2.5*100-1*12.5
=250-12.5
=237.5

2．5＊（4＋8）＊12．5简算

2．5＊（4＋8）＊12．5
=2.5*12*12.5
=2.5*4*3*12.5
=10*12.5*3
=125*3
=375

2.25-2.5÷12.5×8简算

2.25-2.5÷12.5×8
=2.25-2.5×（1/12.5）×8
=2.25-1/5×8
=2.25-1.6
=0.65
