Question 29251
First put them in mixed fractions;
7{{{1/15}}}={{{112/15}}}
3{{{1/5}}}={{{16/5}}}
Now divide;
{{{112/15}}}/{{{16/5}}}
When you divide fractions, the first thing is to find the reciporical of the second fraction and then multiply;
({{{112/15}}})({{{5/16}}}); 
{{{560/240}}}; reduce;
{{{7/3}}}
