    K=1/5=0.200

    rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation.

    2/5 - (2/10+k) = 0

    2/5 = 2/10 + k

    multiply both sides (each term) by 10, we get

    10*2/5 = 10 * 2/10 + k * 10

    4 = 2 + 10k

    OR 10k = 4 - 2

    10 k = 2

    k = 2 / 10

    Or k = 1/5
