a. \(x-\dfrac{3}{2}=\dfrac{5}{6}\)
\(x=\dfrac{5}{6}+\dfrac{3}{2}\)
\(x=\dfrac{14}{6}=\dfrac{7}{3}\)
b. \(\dfrac{2}{5}\) x \(x=\dfrac{2}{3}\)
\(x=\dfrac{2}{3}:\dfrac{2}{5}\)
\(x=\dfrac{2}{3}\) x \(\dfrac{5}{2}\)
\(x=\dfrac{5}{3}\)
`x - 3 / 2 = 5 / 6`
`x = 5 / 6 + 3 / 2`
`x = 5 / 6 + 9 / 6`
`x = 14 / 6 = 7 / 3` Vậy `x = 7 / 3`
_______________________________
`2 / 5 xx x = 2 / 3`
`x = 2 / 3 : 2 / 5`
`x = 2 / 3 . 5 / 2`
`x = 5 / 3` Vậy `x = 5 / 3`
______________________________
`2 / 5 : x = 1 / 3`
`x = 2 / 5 : 1 / 3`
`x = 2 / 5 . 3`
`x= 6 / 5` Vậy `x = 6 / 5`
_______________________________
`x : 5 / 11 = 22`
`x = 22 . 5 / 11`
`x = 10` Vậy ` x = 10`
c. \(\dfrac{2}{5}:x=\dfrac{1}{3}\)
\(x=\dfrac{2}{5}:\dfrac{1}{3}\)
\(x=\dfrac{2}{5}\) x \(3\)
\(x=\dfrac{6}{5}\)
d. \(x:\dfrac{5}{11}=22\)
\(x=22\) x \(\dfrac{5}{11}\)
\(x=10\)
\(x-\dfrac{3}{2}=\dfrac{5}{6}\)
\(x=\dfrac{5}{6}+\dfrac{3}{2}\)
\(x=\dfrac{14}{6}=\dfrac{7}{3}\)
==================
\(\dfrac{2}{5}\times x=\dfrac{2}{3}\)
\(x=\dfrac{2}{3}:\dfrac{2}{5}\)
\(x=\dfrac{2}{3}\times\dfrac{5}{2}\)
\(x=\dfrac{5}{3}\)
===============
\(\dfrac{2}{5}:x=\dfrac{1}{3}\)
\(x=\dfrac{2}{5}:\dfrac{1}{3}\)
\(x=\dfrac{2}{5}\times3\)
\(x=\dfrac{6}{5}\)
================
\(x:\dfrac{5}{11}=22\)
\(x=22\times\dfrac{5}{11}\)
\(x=\dfrac{110}{11}\)
\(x=10\)
