5.4X除以0.4等于0.5除以3/5,x是多少?

5.4x/0.4=0.5/0.6
所以 5.4x*0.6=0.5*0.4
所以 x=(0.5*0.4)/(5.4*0.6)
x=5/81

5.4x/0.4=0.5/(3/5)
5.4x/0.4=（0.5*5）/3
3*5.4x=0.4*0.5*5
16.2x=1
x=5/81

晕
只小的上网
5.4X/0.4=0.5*5/3
5.4X/0.4=2.5/3
1.8X/0.4=2.5
9X/2=2.5
X=5/9

5.4x/0.4=0.5/(3/5)
两边乘0.4*(3/5)
5.4x*(3/5)=0.5*0.4
4.8x=0.2
x=0.2/4.8
所以x=1/24

1/45

5.4x/0.4=0.5/(3/5)
两边同乘0.24(0.4*3/5)，得
5.4x*0.6=0.5*0.4
4.8x=0.2
x=0.2/4.8
x=1/24
所以x是1/24

把以上文字写成式子为
5.4x/0.4=0.5/(3/5)
两边同乘0.24(0.4*3/5)，得
5.4x*0.6=0.5*0.4
4.8x=0.2
x=0.2/4.8
x=1/24
所以x是1/24

27X/5:2/5=1/2:3/5
27X/5*3/5=2/5*1/2
81X/25=1/5
X=1/5*25/81
X=5/81

5.4x/0.4=0.5*5/3
54x=0.5*5*4/3
54x=10/3
x=10/(3*54)
x=5/81
