56乘10.1用简便的方法计算

56*10.1 =56*(10+0.1) =560+5.6 =565.6

54×10.1 =54×(10+0.1) =54×10+54×0.1 =540+5.4 =545.4

0.56×(10+0.1)=5.6+0.056=5.656

7.56x10.1 =7.56x10+7.56x0.1 =75.6+0.765 =76.365

=65乘(10+0.1)=65乘10+65乘0.1=650+6.5=656.5

5.2×10.1简便计算过程是: 5.2×10.1 =5.2×(10+0.1) =5.2×10+5.2×0.1 =52+0.52 =52.52 解题分析:被乘数进行拆分无法使乘法简便,所以来分析乘数,因为乘数是可以拆成10和0.1的这两个数,而且这两个数与别的数相乘是十倍与0.1倍的关系,所以计...

17.5×10+17.5×0.1=176.75

原式=6.3*(10+0.1) =6.3*10+6.3*0.1 =63+0.63 =63.63

你好,可以先用26×10算出等于260。在用260×0.1=26.希望你满意!
