\n" ); document.write( "x = a positive whole number from the set {1,2,3,4,...}
\n" ); document.write( "2x = number of people who wear glasses
\n" ); document.write( "5x = number of people in class\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This forms the ratio 2x:5x and it reduces fully to 2:5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If 2x people wear glasses out of 5x total, then 5x-2x = 3x people do not wear glasses.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We have 5 people who initially didn't wear glasses, but now do.
\n" ); document.write( "The glasses count goes from 2x to 2x+5
\n" ); document.write( "The non-glasses count goes from 3x to 3x-5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We then get to the ratio glasses:nonGlasses = (2x+5):(3x-5)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Unfortunately there isn't enough information to determine x.
\n" ); document.write( "This means we cannot determine a numeric ratio based on the current given information.\r
