(3又3/4-90.2+ 1/3 )×4.5÷(7.05+6又9/20)
=(3又3/4-90.2+ 1/3 )×4.5÷13.5
=(3又3/4-90.2+ 1/3 )×1/3
=5/4-30-1/15+1/9
=5/4-30+2/45
=233/180-30
=-28又127/180
[(1/3+4.8÷1又3/5)-2又2/3]×1又二分之一
=(1/3+4.8÷1又3/5)×1又二分之一 - 2又2/3×1又二分之一
=1/3×1又二分之一+4.8÷1又3/5×1又二分之一-2
=1/2+9/2-2

0.4×125×25×0.8
=(0.4×25)×(125×0.8)
=10×100=1000
1.25×(8+10)
=1.25×8+1.25×10
=10+12.5=22.5
9123-(123+8.8)
=9123-123-8.8
=9000-8.8
=8991.2
1.24×8.3+8.3×1.76
=8.3×(1.24+1.76)
=8.3×3=24.9
9999×1001
=9999×(1000+1)
=9999×1000+9999×1
=10008999
14.8×6.3-6.3×6.5+8.3×3.7
=(14.8-6.5)×6.3+8.3×3.7
=8.3×6.3+8.3×3.7
8.3×(6.3+3.7)
=8.3×10
=83
1.24+0.78+8.76

分式方程计算题40道,要有答案,急用
1. 3/2x=-2
3=-4x
x=-3/4
2. x/(x-1)+2/(x+1)=1
x(x+1)+2(x-1)=(x-1)(x+1)
x^2+x+2x-2=x^2-1
3x=1
x=1/3
3. 1/(x+1)-x^2/(x^2+3x+2)=-1
1/(x+1)-x^2/(x+1)(x+2)=-1
(x+2)/(x+1)(x+2)-x^2(x+1)(x+2)=-1
x+2-x^2=-(x+1)(x+2)
x^2-x-2=x^2+3x+2
4x=-4
x=-1
x/(2x-1)=(-2x-1)/(1-2x)
x=2x+1
x=-1
(3) (11-2x)/(4-x)=(1-x)/(x-4)
11-2x=x-1
3x=12
x=4
∵当x=4时,原方程无意义,
∴原方程无解
7/(x2+x)+3/(x2-x)=6/(x2-1)
解 方程两边同乘以最简公分母x(x+1)(x-1),得
7(x-1)+3(x+1)=6x
去括号,得 7x-7+3x+3=6x
移项,得7x-6x+3x=7-3
合并同类项,得4x=4
系数化1,得x=1
3/x-6/(1-x)-(x+5)/x(1-x)=0
解 方程两边同乘以最简公分母x(1-x),得
3(1-x)-6x-(x+5)=0
去括号,得 3-3x-6x-x-5=0
合并同类项,得-10x=2
系数化1,得x=-1/5
(5x-4)/(2x-4)=(2x+5)/(3x-6)-1/2
解 方程两边同乘以最简公分母6(x-2),得
3(5x-4)=2(2x+5)-3(x-2)
去括号,得 15x-12=4x+10-3x+6
移项,得15x-4x+3x=10+6+12
合并同类项,得14x=28
系数化1,得x=2
经检验,X=2是增根,舍去,所以原方程无解
x2-4x/(x2-1)+1=2x/(x+1)
解 方程两边同乘以最简公分母(x2-1),得
x2-4x+x2-1=2x(x-1)
即 2x2-4x-1=2x2-2x
移项,得2x2-4x-2x2+2x=1
合并同类项,得-2x=1
x=-1/2
1/(x+3)+1/(6-2x)=(3x-15)/(2x2-18)
解 方程两边同乘以最简公分母2(x+3)(x-3),得
2(x-3)-(x+3)=3x-15
去括号,得2x-6-x-3=3x-15
移项,得2x-x-3x=-15+6+3
合并同类项,得-2x=-6
x=3
解关于x的方程:
x/(x-a)=1-[a/(x+b)] (a≠0)
解:x/(x-a)+[a/(x+b)]=1
通分,(x2+bx+ax-a2)/[(x-a)(x+b)]=1
方程两边同乘以最简公分母(x-a)(x+b),得
(x2+bx+ax-a2)=(x-a)(x+b)
去括号,得x2+bx+ax-a2=x2+bx-ax-ab
移项,得x2+bx+ax-x2-bx+ax=-ab+a2
合并同类项,得2ax=a2-ab
x=(a-b)/2
