Find the Number.
~~~~~~~~~~~~~~~~~



        The equation,  which @josgarithmetic tries to sell you,   highlight%28cross%2813%2F%288-p%29=2%2F5%29%29,   is incorrect.
        So, even do not try to solve it  ( ! )

        I came to bring you a correct solution.


The correct equation is

    %2813-p%29%2F8 = 2%2F5


Cross multiply, simplify and find "p"

    5*(13-p) = 2*8

    65 - 5p = 16

    65 - 16 = 5p

       49   = 5p

        p   = 49/5     ANSWER

Solved.
