Tìm x, biết:

\(\Large\dfrac{7}{13}:x = \dfrac{14}{39}\)

• A. \(\Large x =\dfrac{1}{2}\)
• B. \(\Large x =\dfrac{2}{2}\)
• C. \(\Large x =\dfrac{3}{2}\)
• D. \(\Large x =\dfrac{4}{2}\)

\(\Large\dfrac{7}{13}:x = \dfrac{14}{39}\)

\(\Large x =\dfrac{7}{13}:\dfrac{14}{39}\)

\(\Large x =\dfrac{7}{13}\times\dfrac{39}{14}\)

\(\Large x =\dfrac{7}{13}\times\dfrac{39}{14}\)

\(\Large x =\dfrac{3}{2}\)
