Question 339967
six and four fifths * two and one half divided by two and three eighths
<pre><b>
{{{6&4/5}}}{{{""*""}}}{{{2&1/2}}}{{{"÷"}}}{{{2&3/8}}}

Change all the mixed numbers to improper fractions:

{{{34/5}}}{{{""*""}}}{{{5/2}}}{{{"÷"}}}{{{19/8}}}

Invert the third fraction and change to multiplication:

{{{34/5}}}{{{""*""}}}{{{5/2}}}{{{""*""}}}{{{8/19}}}

Cancel the 5's

{{{34/cross(5)}}}{{{""*""}}}{{{cross(5)/2}}}{{{""*""}}}{{{8/19}}}

Cancel the 2 into the 34, getting 17 on top:

{{{17}}}
{{{cross(34)/cross(5)}}}{{{""*""}}}{{{cross(5)/cross(2)}}}{{{""*""}}}{{{8/19}}}

That's all the will cancel, so we have

{{{(17*8)/19}}}

{{{136/19}}}

Change to a mixed number:

{{{7&3/19}}}
