we are given

[tex] \frac{4}{5}n -\frac{1}{5} =\frac{2}{5}n [/tex]

Firstly , we will multiply both sides by 5

[tex] 5*\frac{4}{5}n -5*\frac{1}{5} =5*\frac{2}{5}n [/tex]

now, we can simplify it

[tex] 4n-1 =2n [/tex]

[tex] 2n =1 [/tex]

now, we can solve for n

[tex] n =\frac{1}{2} [/tex].............Answer
