Let  $ABC$  be an equilateral triangle with side length  $1$ . This triangle is rotated by some angle about its center to form triangle  $DEF.$  The intersection of  $ABC$  and  $DEF$  is an equilateral hexagon with an area that is  $\frac{4} {5}$  the area of  $ABC.$  The side length of this hexagon can be expressed in the form  $\frac{m}{n}$  where  $m$  and  $n$  are relatively prime positive integers. What is  $m+n$ ?
