Question

x : 2 - x : 5 = 25

Nhanh ạ

Answer 1

\(=>x=25:\left(\dfrac{1}{2}-\dfrac{1}{5}\right)=25:\dfrac{3}{10}=\dfrac{250}{3}\)

Answer 2

\(\dfrac{x}{2}-\dfrac{x}{5}=25\)

\(\dfrac{5x}{10}-\dfrac{2x}{10}=25\)

\(\dfrac{5x-2x}{10}=25\)

\(\dfrac{3x}{10}=25\)

\(3x=10.25\)

\(3x=250:3\)

\(3x=\dfrac{250}{3}\)
