Question

4.25×0.16+264×0.0425+5.2×4.25等于多少？急急

Answer 1

原式=4.25×0.16+4.25×2.64+4.25×5.2
=4.25×（0.16+2.64+5.2）
=4.25×8
=17/4×8
=34
观察题目的特点，发现每一项都含有4.25这个因式（第二项0.0425可以通过乘100变成4.25），然后运用提公因式法进行结算。

Answer 2

4.25×0.16+264×0.0425+5.2×4.25等于34
4.25×0.16+264×0.0425+5.2×4.25
=4.25×（1×0.16+264×0.01+5.2×1）
=4.25×（0.16+2.64+5.2）
=4.25×8
=34

Answer 3

4.25×0.16+264×0.0425+5.2×4.25=4.25×0.16+4.25×2.64+4.25×5.2=4.25×(0.16+2.64+5.2)=4.25×8=34。这样计算比较简便。

Answer 4

这道题是这样算的：
4.25ⅹ0.16+264x0.0425+5.2x4.25
=4.25ⅹ0.16+2.64x4.25+5.2ⅹ4.25
=4.25ⅹ（0.16+2.64+5.2）
=4.25ⅹ8
=34

Answer 5

解: 此题可用提取公因数的方法来解，关键是264×0.0425这项，把它变换成2.64×4.25。
原题=4.25×(0.16+2.64+5.2)
=4.25×8
=34
