x : 0,125 + x : 0,5 + x : 0,25 = x : 0,5 + 165
x : 8 + x : 2 + x : 4 = x : 2 + 165
x : x : 8 + x : 2 + x : 4 = 2 + 165
1 : 8 + x : 2 + x : 4 = 167
8 + x : [ 2 + 4 ] = 167
8 + x : 6 + 167
x : 6 = 167 - 8
x : 6 = 159
x = 159 : 6
x = 26.5

\(x\cdot4+x\cdot8+x\cdot2=140\\ x\cdot\left(4+8+2\right)=140\\ x=10\)

x : 0,25 + x : 0,5 + x : 0,125 = 24
\(x\) x 4 + \(x\) x 2 + \(x\) x 8 = 24
\(x\) x (4 + 2 + 8) = 24
\(x\) x 14 = 24
x = 24 : 14
x = 1(dư 10)
Lời giải:
$x:0,25+x:0,5+x:0,125=24$
$x\times 4+x\times 2+x\times 8=24$
$x\times (4+2+8)=24$
$x\times 14=24$
$x=24:14=\frac{12}{7}$

X : (1+0,5+0,25+0,125)=2022
X : 1,875 = 2022
X = 1078,4
x+x:0,5+x:0,25+x:0,125 = 2022
x.(1+1/2+1/4+1/8) = 2022
x.15/8 = 2022
x = 2022: 15/8
x = 1078,4

5,78 x 0 ,5 = 2,89

k me nha
5,78 x 0,5 = 5,75 :2=2,89
4,56 x 0,25= 4,56:4=1,14
48,08 x 0,125=48,08 : 8=6,01
5,78 : 0,5 =5,78x2=11,56
4,56 : 0,25=4,56x4=18,24
48,08 : 0,125=48,08 x8=384,64
