9.99x2.22+3.33x3.34的简算怎么做？

Answer 1

将9.99拆成3.33乘以3，提取相同的乘数3.33后，计算2.22×3+2.34得到结果9，再用9×3.33得到结果29.97。

Answer 2

这道题可以通过提取公因数的方法来简便计算，具体计算过程如下：
9.99x2.22+3.33x3.34
=3.33x3x2.22+3.33x3.34
=3.33x(6.66+3.34)
=3.33x10
=33.3

Answer 3

答:9.99x2.22+3.33x3.34
=3x3.33x2.22+3.33x3.34
=6.66x3.33+3.33+3.34
=10x3.33
=33.3

Answer 4

9.99×2.22＋3.33×3.34
＝3.33×3×2.22＋3.33×3.34
＝3.33×6.66＋3.33×3.34
＝3.33×(6.66＋3.34)
＝3.33×10
＝33.3

Answer 5

9.99x2.22+3.33x3.34＝3x3.33x2.22+3.33x3.34＝6.66x（3.33+3.33+3.34）＝10x3.33＝33.3
