35.4x0.48十6.74x4.8一0.048简便方法？

Answer 1

简便计算方法如下

1、提取原式: 35.4x0.48十6.74x4.8一0.048

2、计算过程: 

=35.4×0.48+67.4×0.48-0.48×0.1

=0.48×( 35.4+67.4-0.1 )

=0.48×（102.8-0.1）

=0.48×102.7

=0.48×100+0.48×2+0.48×0.7

=48+0.96+0.336

=48+1.296

=49.296

3、计算结果: 49.296

4、谢谢，期待您的采纳！

Answer 2

35.4x0.48十6.74x4.8一0.048
=0.48x(35.4+67.4-10)
=0.48x92.8
=0.5x92.8-92.8x0.02
=46.4-1.856
=44.544

Answer 3

35.4×0.48+6.74×4.8-0.048
=35.4×0.48+67.4×0.48-0.1×0.48
=（35.4+67.4-0.1）×0.48
=102.7×0.48
=102.7×（0.5-0.02）
=51.35-2.054
=49.296

Answer 4

这道题的简便计算方法是：35.4*0.48+6.74*4.8-0.048=0.048（354+674-1）=0.048*1027=49.296。

Answer 5

解：35.4×0.48＋6.74×4.8－0.048
=35.4×0.48×（10÷10）＋6.74×4.8×（100÷100）－0.048
=35.4×10×0.48÷10＋6.74×100×4.8÷100－0.048
=354×0.048＋674×0.048－0.048
=0.048×（354＋674－1）
=0.048×1027
=（0.05-0.002）×1027
=51.35-2.054
=49.296
先运用乘法结合律，然后提取公因数，最后再用乘法分配律，达到快速口算。
