Question

5.4×1.25×0.5×0.8简便计算？

Answer 1

5.4*1.25*0.5*0.8
＝2.7*（2*0.5）*（1.25*0.8）
＝2.7*1*1
＝2.7

Answer 2

5.4×1.25×0.5×0.8
=2.7×(2×0.5)×(1.25×0.8)
=2.7×1×1
=2.7

因为五点4=2×2点七，二，乘以零点5=11点25×0点8=1，所以用简便计算就好

Answer 3

你好，同学
简便算法过程如下
5.4x1.25x0.5x0.8
=（5.4x0.5）x（1.25x0.8）.
=2.7x1
=2.7
希望可以帮到你

Answer 4

解:5.4×1.25×0.5×0.8=5.4×0.5×1.25×0.8=2.7×1=2.7

Answer 5

原式=0.54x1.25x0.5x8=0.54x1.25x0.5x2x4=0.54x（1.25x4）x（0.5x2）=0.54x5=2.7。完毕。
