Question 7018
In 8 {{{18/24}}}, Ignore the 8 for now and focus on {{{18/24}}}.  What is the GCF in both 18 & 24? 


18=6x3
24=6x4


Since you see 6 in both 18  & 24, you can cross 6 out from both the numerator and the denominator...then {{{18/24}}}= {{{3/4}}}

{{{3/4}}} cannot be reduced any further.  

Now, remember the 8 that we put to the side earlier...bring that back in and you get:
8 {{{3/4}}}.
