Question 931339
 2 1/4 is a mixed fraction
first of all we have to convert it into a simple fraction
  {{{2 1/4  =  ( 4*2+1)/4}}}
              =9/4
so {{{-1/3 ÷ 2 1/4  = (-1/3) /(9/4)}}}
                     ={{{ (-1/3)*(4/9)}}}
                           ={{{(-1*4)/(3*9)}}}
                           ={{{-4/27}}}
     Result is -4/27
