Question

x+25%x=1 3/8

Answer 1

`x + 25%x = 1 3/8`

`=> 5/4x = 11/8`

`=> 10/8x = 11/8`

`=> x = 11/8:10/8`

`=> x = 11/10`

Vậy `...`

Answer 2

\(x+25\%x=1\dfrac{3}{8}\)

\(x+\dfrac{1}{4}x=\dfrac{11}{8}\)

\(x.\left(\dfrac{1}{4}+1\right)=\dfrac{11}{8}\)

\(x.\dfrac{5}{4}=\dfrac{11}{8}\)

\(x=\dfrac{11}{8}:\dfrac{5}{8}\)

\(x=\dfrac{11}{8}\times\dfrac{8}{5}\)

\(x=\dfrac{11}{10}\)

\(Vẫy=\dfrac{11}{10}\)
