As posted, I interpret \"the third\" to mean the third number in a list of numbers,
\n" ); document.write( "where the first, second, and third are in the ratio 4:5:6 respectively.
\n" ); document.write( "That will not yield 3 integers, but fractions are numbers too.
\n" ); document.write( "
\n" ); document.write( "Let the numbers be \"4x\" , \"5x\" , and \"6x\" .
\n" ); document.write( "That makes sure that they are in the ratio of 4:5:6.
\n" ); document.write( "\"6x%2B4x=10x\" is the sum of the largest and the smallest.
\n" ); document.write( "\"6x%2B55\" is the sum of the third and 55.
\n" ); document.write( "So, the equation to solve is
\n" ); document.write( "\"10x=6x%2B55\"
\n" ); document.write( "\"10x-6x=55\"
\n" ); document.write( "\"4x=highlight%2855%29\" is the smallest number
\n" ); document.write( "From \"4x=55\" we get
\n" ); document.write( "\"x=55%2F4\"
\n" ); document.write( "\"5x=5%2855%2F4%29=highlight%28275%2F4%29\" , and
\n" ); document.write( "\"6x=6%2855%2F4%29=6%2A55%2F4=3%2A55%2F2=highlight%28165%2F4%29\" .
\n" ); document.write( "
\n" );
