[tex] \frac{5}{6} k = \frac{1}{6} [/tex]
Refine
[tex] \frac{5}{6} k = \frac{5k}{6} [/tex]
[tex] \frac{5k}{6} = \frac{1}{6} [/tex]
Multiply both sides by 6 :
[tex] \frac{5k}{6} *6= \frac{1}{6} *6[/tex]
[tex]5k = 1[/tex]
Divide both sides by 5 :
[tex] \frac{5k}{5} = \frac{1}{5} [/tex]
[tex]k= \frac{1}{5} [/tex]
hope this helps!
