Question 854633
Let's first find a common denominator.  What number do both 8 and 6 go into?  Let's use 24.
{{{5/8}}}or{{{15/24}}} of the figures are cranes.
The remainder is {{{9/24}}} [{{{24/24}}}-{{{15/24}}}], reduced to {{{3/8}}} 
{{{1/6}}}of{{{3/8}}} are frogs. [1/6 of the remainder are frogs.]
Therefore, {{{5/6}}}of the remainder{{{3/8}}} are grasshoppers.
Multiply across - {{{5/6}}}*{{{3/8}}}={{{15/48}}}
Can that be reduced?  Yes, 3 goes into both numerator and denominator.  {{{5/16}}}
