Question

4.56×3.77+45.6×0.613+0.456-1怎么简便运算？

Answer 1

你可以先把式子变形，再用乘法分配率简便运算
4.56×3.77+45.6×0.613+0.456-1
= 4.56×3.77+4.56×6.13+4.56×0.1-1
=4.56×（3.77+6.13+0.1）-1
=4.56×10-1
=45.6-1
=44.6

Answer 2

根据题意，这道题用到的简便计算方法是乘法分配律和乘法结合律，计算方法如下：原式=4.56*3.77+4.56*6.13+4.56*0.1-1=4.56*（3.77+6.13+0.1）-1=4.56*10-1=44.6。

Answer 3

有你把题打出来的时间，都算出来了！
4.56*3.77+45.6*0.613+0.456-1
=4.56*3.77+4.56*6.13+0.456-1
=4.56*（3.77+6.13）+0.456-1
=4.56*（3.77+6.13+0.1-0.1）+0.456-1
=4.56*（10-0.1）+0.456-1
=45.6-1
=44.6

Answer 4

4.56×3.77＋45.6×0.613＋0.456－1
＝4.56×3.77＋4.56x6.l3十4.56×0.l－l
＝4.56×（3.77＋6.13十0.1）－l
＝4.56×10－1
＝45.6一1
＝44.6

Answer 5

4.56×3.77+45.6×0.613+0.456-1
=45.6×0.377+45.6×0.613+0.456-1
=45.6（0.377+0.613）+0.456-1
=45.6×1+0.456-1
=45.6-0.544
=44.056
