Question 7388
Is your question {{{(3/8)}}}y=2{{{3/4}}}?
IF so:

Multiply both sides by the reciprocal of {{{3/8}}} which is {{{8/3}}}.
{{{8/3}}}*{{{(3/8)}}}y=2{{{3/4}}}*{{{8/3}}}


Then you'll get: 
y=2{{{3/4}}}*{{{8/3}}}


Next, put the mixed number 2{{{3/4}}} in fraction form:  {{{11/4}}}


Then you get: 
y={{{11/4}}}*{{{8/3}}}


y={{{22/3}}}


y=7{{{1/3}}}
