    set up a ratio ...

    \frac{3 \, acres}{7 \, gal} = \frac{x \, acres}{16 \, gal}

    solve for x

    Then why is it telling me that \frac{48}{7}
    Is the same as 6\frac{6}{7} they give different results

    Mixed fractions should be banished in my opinion

    \dfrac{48}{7} = \dfrac{42+6}{7} = \dfrac{42}{7} + \dfrac{6}{7} = 6 + \dfrac{6}{7} = 6\dfrac{6}{7}
