If `a_(1),a_(2),...,.,a_(10)` are positive numbers in arithmetic progression such that `(1)/(a_(1)a_(2))+(1)/(a_(2)a_(3))+...*+(1)/(a_(9)a_(10))=(9)/(64)` and `(1)/(a_(1)a_(10))+(1)/(a_(2)a_(9))+......(1)/(a_(10)a_(1))=(1)/(10)((1)/(a_(1))+...+(1)/(a_(10)))` then the value of `(2)/(5)((a_(1))/(a_(10))+(a_(10))/(a_(1)))` is
