Let n/d be the fraction. Then by the given, d = n + 5, and \"%28n+-+4%29%2F%28d+%2B+3%29+=+1%2F5\". By direct substitution, \"%28n+-+4%29%2F%28n%2B5+%2B+3%29+=+1%2F5\", or
\n" ); document.write( "\"%28n-4%29%2F%28n+%2B+8%29+=+1%2F5\".
\n" ); document.write( "5(n - 4) = n + 8, or
\n" ); document.write( "5n - 20 = n + 8, or
\n" ); document.write( "4n = 28, or
\n" ); document.write( "n = 7, and d = 12. The original fraction is 7/12.
\n" ); document.write( "
