    umm...why do you keep substituting different measurements into your equation. Why not just do ratios?

    Which is bigger--mile or meter? mile, of course.
    Hence, \frac{mile}{meter}=\frac{1609}{1}

    In measurements, ratios are equal to 1,
    an example: 1 mile = 1609 meters, therefore you write the ratio as \frac{1mile}{1609meters} such as if I wanted to convert meters to miles I would do this...

    1609m_e=1609m_e

    1609m_e\times1=1609m_e\times\frac{1m_i}{1609m_e}

    1609m_e=\frac{1609m_im_e}{1609m_e}

    1609m_e=\frac{<br />
\not{1609}m_i\not{m_e}}{\not{1609}<br />
\not{m_e}}

    1609m_e=1m_i

    admitedly I can just substitute 1 mile for 1609 meters, but that is not what the way the person who asked this question wants.
