1.25×0.32×1.25简便计算求解答

Answer 1

1.25x0.32x1.25=(1.25x0.8)x(0.4x1.25)=1x0.5=0.5

Answer 2

1.25×0.32×1.25

=（1.25×0.8)*(0.4×1.25)

=1*0.5
=0.5

Answer 3

1.25×0.32×1.25

=（1.25×0.8)X(0.4×1.25)

=1X0.5
=0.5

Answer 4

1.25×0.32×1.25
= 1.25×32/100×1.25
= 1.25×64/200×1.25
= 1.25×8×8/200×1.25
= 10×8/200×1.25
= 10×1/200×10
