Question 920917
take 3 away from the number and multiply the result by 2,
the final result is equal to a quarter of the number.
:
2(n - 3) = {{{1/4}}}n 
multiply both sides by 4
8(n - 3) = n
8n - 24 = n
8n - n = 24
7n = 24
n = 24/7
:
Not an integer, check and see if this is true
 2({{{24/7}}} - 3) = {{{1/4}}}*{{{24/7}}}
  2({{{24/7}}} - {{{21/7}}}) = {{{24/28}}}
   2({{{3/7}}}) = {{{24/28}}}
  {{{6/7}}} = {{{24/28}}}; the same fractions
