Question

Tìm \(\dfrac{a}{b}\)

\(\dfrac{a}{b}x4+\dfrac{1}{6}=\dfrac{19}{6}\)

b) \(\dfrac{4}{5}:\dfrac{a}{b}x6=\dfrac{16}{5}\)

Answer 1

\(a)\)\(\dfrac{a}{b}\times4+\dfrac{1}{6}=\dfrac{19}{6}\)

   \(\dfrac{a}{b}\times4=\dfrac{19}{6}-\dfrac{1}{6}\)

   \(\dfrac{a}{b}\times4=\dfrac{18}{6}\)

   \(\dfrac{a}{b}=\dfrac{18}{6}\div4\)

   \(\dfrac{a}{b}=\dfrac{18}{6}\times\dfrac{1}{4}\)

\(\dfrac{a}{b}=\dfrac{18}{24}\)
