Sara is 1/6 as old as Donald. \r
\n" ); document.write( "\n" ); document.write( "\"Donald=d\"
\n" ); document.write( "\"Sarah=%281%2F6%29d\"\r
\n" ); document.write( "\n" ); document.write( "In 6 years, Sarah's age will be 11 years more than 1/5 of Donald's age.\r
\n" ); document.write( "\n" ); document.write( "\"Sarah%2B6=%281%2F5%29%28Donald%2B6%2B11%29\"
\n" ); document.write( " or
\n" ); document.write( "\"%281%2F6%29d%2B6=%281%2F5%29%28d%2B6%2B11%29\"\r
\n" ); document.write( "\n" ); document.write( "Multiply both sides by 5.\r
\n" ); document.write( "\n" ); document.write( "\"%285%2F6%29d%2B30=%28d%2B6%2B11%29\"\r
\n" ); document.write( "\n" ); document.write( "Subtract 30 from both sides.\r
\n" ); document.write( "\n" ); document.write( "\"%285%2F6%29d=d-13\"\r
\n" ); document.write( "\n" ); document.write( "Subtract d from both sides.\r
\n" ); document.write( "\n" ); document.write( "\"-%281%2F6%29d=-13\"\r
\n" ); document.write( "\n" ); document.write( "Eliminate the negatives.\r
\n" ); document.write( "\n" ); document.write( "\"%281%2F6%29d=13\"
\n" ); document.write( "*Therefore Sarah=13.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply both sides by 6.\r
\n" ); document.write( "\n" ); document.write( "\"d=78\"\r
\n" ); document.write( "\n" ); document.write( "*Therefore Donald=78\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check: \"%281%2F6%29d%2B6=%281%2F5%29%28d%2B6%2B11%29\" = \"%2813%2B6%29=%281%2F5%29%2895%29\" or \"19=95%2F5\". It's true!\r
