Answer 1

解0.125x500x0.2x8
=0.125x8×500×0.2
=1×500×0.2
=100
12.5x0.56x0.4x0.8x250
=12.5x0.8x0.4x250x0.56
=10*0.4x250x0.56
=10*100*0.56
=56*10
=560
(291-38x3.5-35.5)/3.5
=291/3.5-38*1-10
=291/3.5-48

Answer 2

0.125x500x0.2x8
=（0.125×8）×（500×0.2）
=1×100
=100

(291-38x3.5-35.5)/3.5
=（291-35.5）/3.5-38×3.5/3.5
=255.5/3.5-38
=73-38
=35

12.5x0.56x0.4x0.8x250
=（12.5×0.8）×（0.4×250）×0.56
=10×100×0.56
=560

Answer 3

0.125x500x0.2x8 98.5-14.82/7.6x3.1
=0.125x8x500x0.2 =98.5-1.95x3.1
=1x100 =98.5-6.045
=100 =92.455
(291-38x3.5-35.5)/3.5
=291/3.5-38x3.5/3.5-35.5/3.5
=291/3.5-133/3.5-35.5/3.5
=(291-133-35.5)/3.5
=122.5/3.5
=35
12.5x0.56x0.4x0.8x250
=12.5x0.8x0.4x250x0.56
=10x100x0.56
=560
