Tiếc thật, biết thế rút coin từ tết rồi...

Nghĩa là bây giờ coin là chỉ đổi ra thành quà thôi ạ?

ĐKXĐ: \(x\ne1;4\)

\(\dfrac{7}{x-1}=\dfrac{5}{x-4}\)

\(\Leftrightarrow7\left(x-4\right)=5\left(x-1\right)\)

\(\Leftrightarrow7x-28=5x-5\)

\(\Leftrightarrow7x-5x=-5+28\)

\(\Leftrightarrow2x=23\)

\(\Leftrightarrow x=\dfrac{23}{2}\)

\(265\%=\dfrac{265}{100}=\dfrac{53}{20}\)
