x:1/4+x:1/8+x:1/2+1=0,90
x*4+x*8+x*2+x*1=0,90
x*(4+8+2+1)=0,90
x*15=0,90
x=0,06
x : 0,25 + x x 11 = 24
x x 4 + x x 11 = 24
x x (4 + 11) = 24
x x 15 = 24
x = 24 : 15
x = 1,6
Chúc bạn học tốt.

Ta có:
\(x:0,25+x.11=24\)
\(x.4+x.11=24\)
\(x\left(4+11\right)=24\)
\(x.15=24\)
\(x=1,6\)
\(x:0,25+x.11=24\)
<=> \(x:\frac{1}{4}+x.11=24\)
<=> \(x.4+x.11=24\) <=> \(x.\left(4+11\right)=24\)
<=> \(15x=24\) <=>\(x=\frac{24}{15}\)
vậy \(x=\frac{24}{15}\)
a, X:0.25+X x 11=24
X x 4 + X x 11 = 24
X x (11 + 4) = 24
X x 15 = 24
X = 24 : 15
X = 1,6
b, X x 8.01-X: 100=38
X x 8,01 - X x 0,01 = 38
X x (8,01 - 0,01) = 38
X x 8 = 38
X = 38 : 8
X = 4,75`
a, X:0.25+X x 11=24
X x 4 + X x 11 = 24
X x (11 + 4) = 24
X x 15 = 24
X = 24 : 15
X = 1,6
b, X x 8.01-X: 100=38
X x 8,01 - X x 0,01 = 38
X x (8,01 - 0,01) = 38
X x 8 = 38
X = 38 : 8
X = 4,75
\(x:0,125+x:0,25-x:20\%-24=11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}-24=11\)
\(8\times x+4\times x-5\times x-24=11\)
\(7\times x=35\)
\(x=5\)
\(\text{x : 0 , 125 + x : 0 , 25 − x : 20 % − 24 = 11}\)
\(x : 0 , 125 + x : 0 , 25 − x : 0 , 2 − 24 = 11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}-24=11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}=24+11\)
\(x:\dfrac{1}{8}+x:\dfrac{1}{4}-x:\dfrac{1}{5}=35\)
\(\text{x ×}\dfrac{8}{1}+x\text{×}\dfrac{ }{ }+\dfrac{4}{1}-x\text{×}\dfrac{5}{1}=35\)
\(x × 8 + x × 4 − x × 5 = 35\)
\(x × ( 8 + 4 − 5 ) = 35\)
\(x × 7 = 35\)
\(x = 35 : 7\)
\(x = 5\)
