Question

4.8✘0.25脱式计算怎么算？

Answer 1

=0.25乘以0.8乘以6=0.2乘以6=1.2

Answer 2

简便计算过程如下
4.8×0.25
＝（4+0.8）×0.25
＝4×0.25+0.8×0.25
＝1+0.2
＝1.2
望采纳

Answer 3

4.8×0.25
=（4+0.8）×0.25
=4×0.25+0.4×0.25×2
=1+0.2
=1.2

Answer 4

4.8x0.25=(1.2x4)x0.25=1.2x4x0.25=1.2x1=1.2

Answer 5

4.8×0.25
＝1.2×4×0.25
＝1.2×1
＝1
这样脱式计算更简便，看到0.25就要想四，所以把4.8分成了1.2×4。
