\(\dfrac{x}{5}=\dfrac{26}{65}\)
\(\dfrac{x}{5}=\dfrac{2}{5}\)
\(x=2\)
______________________________________________
\(\dfrac{3}{x}=\dfrac{51}{85}\)
\(\dfrac{3}{x}=\dfrac{3}{5}\)
`x=5`

\(=\frac{26}{7}x\left(\frac{11}{3}-\frac{8}{3}\right)\)
\(=\frac{26}{7}x1\)
\(=\frac{26}{7}\)

\(a,\dfrac{x}{3}=\dfrac{10}{15}\\ \Rightarrow\dfrac{x}{3}=\dfrac{2}{3}\\ \Rightarrow x=2\\ b,\dfrac{x}{5}=\dfrac{26}{65}\\ \Rightarrow\dfrac{x}{5}=\dfrac{2}{5}\\ \Rightarrow x=2\)
a, \(\dfrac{x}{3}=\dfrac{10}{15}\Leftrightarrow\dfrac{5x}{15}=\dfrac{10}{15}\Rightarrow x=2\)
b, \(\dfrac{x}{5}=\dfrac{26}{65}\Leftrightarrow\dfrac{13x}{65}=\dfrac{26}{65}\Rightarrow x=2\)

Vì \(\frac{x}{4}\)= \(\frac{26}{23}\)nên x.23 = 4.26 \(\Rightarrow\) x= \(\frac{4.26}{23}\)\(\Rightarrow\)x= ???
Bài này ko chia hết được bạn ạ....bn xem lại đề nhé..
Quy đồng mẫu số ta có \(\frac{x}{92}=\frac{104}{92}\)
Suy ra \(x=104\)

\(\dfrac{x}{5}=\dfrac{26}{65}\)
\(\Leftrightarrow65x=130\)
\(\Leftrightarrow x=2\)
\(\dfrac{3}{x}=\dfrac{51}{85}\)
\(\Leftrightarrow51x=255\)
\(\Leftrightarrow x=5\)
`x/5=26/65`
`65xx x=5xx26`
`65xx x=130`
`x=130:65=2`
`3/x=51/85`
`51xx x=3xx85`
`51xx x=255`
`x=255:51=5`
\(\frac{x}{5}=\frac{26}{65}\)
\(x:5=\frac{26}{65}\)
\(x=\frac{26}{65}\times5\)
\(x=2\)
Vậy x = 2
x là
5 x 26 : 65 = 2
Vậy x = 2
