42.3×0.73+2.7×4.23简便计算方法？

Answer 1

42.3×0.73+2.7×4.23=4.23×7.3+4.23×2.7=4.23×（7.3+2.7）=4.23×10=42.3

Answer 2

简便计算方法如下：
42.3X0.73+2.7X4.23
=42.3X0.73+42.3X0.27
=42.3X（0.73+0.27）
=42.3X1
=42.3

Answer 3

42.3×0.73+2.7×4.23=4.23×10×0.73+2.7×4.23=4.23×(10×0.73+2.7)=4.23×10=42.3

Answer 4

42.3x0.73+2.7x4.23=4.23x7.3+2.7x4.23=4.23(7.3+2.7)=4.23x10=42.3

Answer 5

42.3×0.73+2.7×4.23=4.23×7.3+4.23×2.7=4.23×（7.3+2.7）=4.23×10=42.3 根据乘法分配率
