Question

2.5乘1.25乘0.32 简便算法

Answer 1

2.5×1.25×0.32
=（2.5×0.4）×（1.25×0.8）
=1×1
=1

Answer 2

=（2.5*0.04）*（1.25*0.08）
=0.1*0.1
=0.01

Answer 3

2.5乘1.25乘0.32 简便算法
=(2.5x0.4)x(1.25x0.8)
=1x1
=1

Answer 4

2.5ⅹ1.25x0.32
=（2.5x0.4）ⅹ（1.25ⅹ0.8）
=1ⅹ1
=1

Answer 5

2.5×1.25×0.32
=2.5×1.25×0.4×0.8
=（2.5×0.4）×（1.25×0.8）
=1×1
=1
