Question

6.4x3.2+36x0.32用简便法做？

Answer 1

6.4x3.2+36x0.32
=6.4x3.2+36÷10x0.32×10
=6.4x3.2+3.6x3.2
=（仿扮6.4+3.6）备森灶春明x3.2
=10x3.2
=32

Answer 2

都有32，所以选择把0.32扩大10倍。
想用散拍贺整个式子不变，冲派把0.32×10就需贺拍要把36÷10=3.6
所以原式等于6.4×3.2+3.6×3.2。
一共也是把3.2提出来。
3.2×（6.4+3.6）=32
简便计算结果32。

Answer 3

简敏耐差亩含便运算桥皮:
6.4×3.2+36×0.32
=6.4×3.2+3.6×3.2
=(6.4+3.6)×3.2
=10×3.2
=32

Answer 4

6.4×3.2+36×0.32
=6.4×3.2+3.6×10×0.32
=6.4×3.2+3.6×3.2
=3.2×（昌伍6.4+3.6）搏迅瞎基空
=3.2×10
=32
