Question

2.6×0.5-1.4×0.6怎么简算？

Answer 1

简算：
2.6×0.5-1.4×0.6
=（2+0.6）×0.5-1.4×0.6（乘法分配律）
=1+0.6×0.5-1.4×0.6
=1-1.4×0.6+0.6×0.5（带符号搬家）
=1-0.6×（1.4-0.5）
=1-0.6×0.9
=1-0.54
=0.46

Answer 2

这个就需要找一下公因数了，没有公因数就自己创造，就是进行数字的拆解，0.6=0.5+0.1, 这样就可以提取公因数啦：
解：2.6×0.5-1.4×0.6

=2.6×0.5-1.4×（0.5+0.1）
=（2.6-1.4）×0.5-0.14
=1.2×0.5-0.14
=0.6-0.14
=0.36

Answer 3

2.6×0.5-1.4×0.6
=2.6×0.5-1.4×(0.5+0.1)
=2.6×0.5-1.4×0.5-1.4×0.1
=0.5×(2.6-1.4)-0.14
=0.5×1.2-0.14
=0.6-0.14
=0.46
