ANSWER
[tex]n=\frac{5}{6} [/tex]
EXPLANATION
The given equation is
[tex] \frac{4}{5}n =\frac{2}{3} [/tex]
We multiply both sides of the equation by:
[tex]\frac{5}{4}[/tex]
[tex] \frac{5}{4}\times \frac{4}{5}n =\frac{2}{3}\times\frac{5}{4} [/tex]
Multiply and cancel out common factors
This implies that:
[tex]n=\frac{5}{6}[/tex]
Option B is correct.
