Question 207300
<pre><font size = 4 color = "indigo"><b>
{{{3}}}÷{{{2&1/4}}}

Write the {{{3}}} as {{{3/1}}}

{{{3/1}}}÷{{{2&1/4}}}

Change {{{2&1/4}}} to an improper fraction {{{9/4}}}
and write that instead:

{{{3/1}}}÷{{{9/4}}}

Now invert {{{9/4}}} and change ÷ to ×

{{{3/1}}}×{{{4/9}}}

Divide the 3 on top by 3 and the 9 on the
bottom by 3:

{{{""^1cross(3)/1}}}×{{{4/(cross(9))[3]))}}}

End up with 

{{{4/3}}}

or as a mixed fraction {{{1&1/3}}}
