简便算法:3.6×80%-36×0.03

简便算法:3.6×80%-36×0.03
简便算法:3.6×80%-36×0.03

简便算法:3.6×80%-36×0.03
3.6×80%-36×0.03
=3.6x0.8-3.6x0.3
=3.6x(0.8-0.3)
=3.6x0.5
=1.8

3.6×80%-36×0.03
=3.6×0.8-3.6×0.3
=3.6×(0.8-0.3)
=3.6×0.5
=1.8

3.6×80%-36×0.03
=3.6×0.8-36×0.03
=36×(0.08-0.03)
=36×0.05
=1.8

3.6×80%-36×0.03
=36*(0.08-0.03)
=36*0.05
=1.8

1.8

=3.6x0.8-3.6x0.3
=3.6x(0.8-0.3)
=3.6x0.5
=1.8

3.6×0.8-3.6×0.3
3.6×(0.8-0.3)
3.6×0.5
1.8

1.8

3.6×80%-36×0.03
=3.6×0.8-36×0.03
=36×(0.08-0.03)
=36×0.05
=1.8

那不就是(0.8-0.3)x3.6么!

36×(0.08-0.03)=36×0.05=1.8

把3.6×80%变成36×0.08.原式等于 36×0.08+36×0.03=36×(0.08+0.03)=36×0.11=36×0.1+36×0.01=3.6+0.36=3.96

3.6×80%-36×0.03
=3.6×0.8-3.6×0.3
=3.6×(0.8-0.3)
=3.6×0.5
=1.8

3.6×80%-36×0.03
=3.6×0.8-3.6×0.3
=3.6×(0.8-0.3)
=3.6×0.5
=1.8
