Question

tìm x biết :

\(\dfrac{13}{3}\): x = -6:\(\dfrac{3}{10}\)

Answer 1

\(\dfrac{13}{3}:x=\left(-6\right):\dfrac{3}{10}\)

\(\Leftrightarrow\dfrac{13}{3}:x=-20\)

\(\Leftrightarrow x=\dfrac{13}{3}:\left(-20\right)\)

\(\Leftrightarrow x=\dfrac{13}{3}:\dfrac{-20}{1}\)

\(\Leftrightarrow x=\dfrac{13}{3}.\dfrac{-1}{20}\)

\(\Leftrightarrow x=\dfrac{-13}{60}\)

Vậy \(x=\dfrac{-13}{60}\)

Answer 2

\(\dfrac{13}{3}\):x=-6:\(\dfrac{3}{10}\)

\(\dfrac{13}{3}\):x= -20

x= \(\dfrac{13}{3}\): (-20)

x= \(\dfrac{13}{3}\): \(\dfrac{-20}{1}\)

x= \(\dfrac{13}{3}\).\(\dfrac{-1}{20}\)

x=\(\dfrac{-13}{60}\)
