Question

3.7乘0.37加3.7乘以0.64加3.7简便运算怎么算？

Answer 1

3.7×0.37+3.7×0.64+3.7
=3.7×(0.37+0.64+1)
=3.7×2.01
=3.7×2+0.037
=7.4+0.037=7.437
用乘法分配率的逆运算和乘法分配率进行简便计算，得到结果为7.437。

Answer 2

3.7×0.37+3.7×0.64+3.7
提取公因式3.7
原式=3.7×（0.37+0.64+1）=3.7×（2+0.01）=7.4+0.037=7.437

Answer 3

3.7×0.37+3.7×0.64+3.7
=3.7×(0.37+0.64+1)
=3.7×2.01
=3.7×(2+0.01)
=3.7×2+3.7×0.01
=7.4+0.037
=7.437

Answer 4

原式=3.7×(0.37+0.64+1)=3.7×2.01=3.7×2+3.7×0.01=7.4+0.037=7.437

Answer 5

3.7x0.37+3.7x0.64+3.7
=3.7x(0.37+0.64)+3.7x1
=3.7x1+3.7x1
=3.7x(1+1)
=3.7x2
=7.4
