Question

2.48×0.56-5.6×0.048怎么简便计算？

Answer 1

原式=2.48*0.56-0.56*0.48
=0.56（2.48-0.48）
=0.56*2
=11.2

Answer 2

原式=2.48*0.56-0.56*0.48
=0.56（2.48-0.48）
=0.56*2
=11.2

Answer 3

提取公因式法更简便
原式＝0.56x2.48-0.56x10x0.048
＝0.56x（2.48-0.48）
＝0.56x2
＝1.12

Answer 4

=2.48×0.56-0.56×0.48
=0.56×(2.48-0.48)
=0.56×2
=1.12

Answer 5

2.48×0.56-0.56×0.48
=0.56×（2.48-0.48）
=0.56×2=1.12
