0.75*3.66-3/4*2.66怎样求值
0.75*3.66-3/4*2.66怎样求值

0.75*3.66-3/4*2.66怎样求值
∵0.75=3/4
∴原式=0.75*3.66-0.75*2.66
∵他们都有0.75
∴提取0.75,得 0.75*(3.66-2.66)=0.75*1=0.75
如果本题有什么不明白可以追问,

0.75*3.66-3/4*2.66
=0.75*3.66-0.75*2.66
=0.75*(3.66-2.66)
=0.75*1
=0.75
祝你开心

0.75*3.66-3/4*2.66
=0.75*3.66-0.75*2.66
=0.75x(3.66-2.66)
=0.75x1
=0.75

0.75*3.66-3/4*2.66
=0.75*(3.66-2.66)
=0.75*1
=0.75
