    hi

    first ly , write 1\frac{1}{5} as an improper fraction ie \frac{6}{5}

    Then \frac{3}{\frac{6}{5}}=3\times \frac{5}{6} .. do you see why ?

    Because when you divide a fraction , it means multiplying its reciprocal .

    Can you continue from where i stopped ?

    thanks for answering, i understand the first bit, would it then be \frac{3}{6} X \frac{5}{6} ?

    nope , its 3\times \frac{5}{6} because

    \frac{3}{\frac{5}{6}}=\frac{\frac{3}{1}}{ \frac{6}{5} }

     <br />
=\frac{3}{1}\times \frac{5}{6}<br />
