4.3x2.7+4.7x7.3 先将4.7拆分成4.3+0.4然后，多次利用乘法分配律来进行简便运算，具体步骤如下
4.3x2.7+(4.3+0.4)x7.3
=4.3x2.7+4.3x7.3+0.4x7.3
=4.3x(2.7+7.3)+0.4x7.3
=4.3x10 +0.4x7.3
=43+2.92
=45.92
4.3x2.7+(4.3+0.4)x7.3
=4.3x2.7+4.3x7.3+0.4x7.3
=4.3x(2.7+7.3)+0.4x7.3
=4.3x10 +0.4x7.3
=43+2.92
=45.92

4.3×2.7+4.7×7.3
=4.3×2.7+（4.3+0.4）×7.3
=4.3×2.7+4.3×7.3+0.4×7.3
=4.3×（2.7+7.3）+2.92
=4.3×10+2.92
=43+2.92
=45.92
=4.3×2.7+（4.3+0.4）×7.3
=4.3×2.7+4.3×7.3+0.4×7.3
=4.3×（2.7+7.3）+2.92
=4.3×10+2.92
=43+2.92
=45.92
