问题描述:

几道计算题,最好有详细的列式!
1.-1-(1+0.5)*1/3/(-4)=
2.(-49/1/9)/1/6=
3.

一.计算题: 1.(1-3/4-7/8)x(-1/5)= 2.(-3又1/3)x(-0.1、(1/4-7/8)*(-1/5)=(-5/8)*(-1/5)=1/8 2、(-10/3)*

1: 1
2: -49/54

1.-1-(1+0.5)*1/3/(-4)
=-1+(3/2)*(1/3)/4
=-1+(1/2)/4
=-1+1/8
=-7/8
2.(-49/1/9)/1/6
=(-49*9)*6
=-441*6
=-2646

1.-1-(3/2)*(1/3)*(-1/4)
=-1+(1/2)*(1/4)
=-1+(1/8)
=-7/8
2.-49*9/(1/6)
=-49*9*6
=-2646
原谅我对原式的理解可能有偏差,希望能帮到你了~
