Question

4.85×6.2-0.62×43.5的简便方法？

Answer 1

你好，这个式子4.85×6.2-0.62×43.5可以等于4.85×6.2-6.2×43.5÷10因为是是两边都有一样的6.2，可以运用加法结合律。等于6.24X(4.85-4.35)=6.24X0.5=3.12。

Answer 2

4.85×6.2-0.62×43.5
=4.85×6.2-6.2×4.35
=6.2×（4.85-4.35）
=6.2×0.5
=3.1
先让两边儿算式中有一个因数相同,用乘法分配率来计算

Answer 3

4.85×6.2-0.62×43.5
＝4.85x6.2一6.2x4.35
＝6.2x（4.85一4.35）
＝6.2x0.5
＝3.1

Answer 4

简便方法如下

Answer 5

4.85*6.2-0.62*3.5
=48.5*0.62-3.5*0.62
=（48.5-3.5）*0.62
=45*0.62
=27.9
