4×5÷4×5=1.
×
×
分析:根據(jù)整數(shù)四則混合運(yùn)算的順序,從左向右進(jìn)行計(jì)算即可.
解答:解:4×5÷4×5,
=20÷4×5,
=5×5,
=25;
所以算式4×5÷4×5=1不對(duì)..
故答案為:×
點(diǎn)評(píng):考查了整數(shù)四則混合運(yùn)算的順序,同一級(jí)運(yùn)算從左向右進(jìn)行計(jì)算.

下面的解方程對(duì)嗎?如果有錯(cuò)誤請(qǐng)改正過來(lái).
(1)4×2.5+4x=56
解:10+4x=56
      14x=56
        x=4
改正:
4×2.5+4x=56,
10+4x=56,
10+4x-10=56-10,
4x=46,
4x÷4=46÷4,
x=11.5;
4×2.5+4x=56,
10+4x=56,
10+4x-10=56-10,
4x=46,
4x÷4=46÷4,
x=11.5;

(2)2x+1.5×2=6
解:2(x+3)=6
  2(x+3)÷2=6÷2
        x+3=3
      x+3-3=3-3
          x=0
改正:
改正:
2x+1.5×2=6
2(x+1.5)=6
2(x+1.5)÷2=6÷2
x+1.5=3
x+1.5-1.5=3-1.5
x=1.5.
改正:
2x+1.5×2=6
2(x+1.5)=6
2(x+1.5)÷2=6÷2
x+1.5=3
x+1.5-1.5=3-1.5
x=1.5.
