Question 1190745
<br>
You need to show the fractions using parentheses.  As you show them, there are numerous possible interpretations.  For example<br>
1. x/y/1/x<br>
That could be...<br>
x/y/1/x = (((x/y)/1)/x) = {{{x/y/1/x}}}
(x/y)/(1/x) = {{{(x/y)/(1/x)}}}
(x/(y/1))/x = {{{(x/(y/1))/x}}}<br>
etc....<br>
