You can put this solution on YOUR website!
I assume that calculating approximate decimal values with a calculator and comparing them is considered cheating.
\n" ); document.write( "The traditional way to compare fractions, is to express them all with a common denominator.
\n" ); document.write( "Sometimes, depending on the particular numbers, there is an easier way, but I do not see an easier way this time.
\n" ); document.write( "\"27=3%2A9=3%2A3%2A3\" is a multiple of \"3\" and a multiple of \"9\",
\n" ); document.write( "but \"27\" has no factor in common with prime number \"5\" ,
\n" ); document.write( "so the least common multiple (the smallest common denominator) is
\n" ); document.write( "\"135=27%2A5=3%2A9%2A5=3%2A%289%2A5%29=3%2A45=9%2A%283%2A5%29=9%2A15\"
\n" ); document.write( "
\n" ); document.write( "\"0.6=6%2F10=3%2F5=3%2A27%2F%285%2A27%29=81%2F135\"
\n" ); document.write( "\"7%2F9=7%2A15%2F%289%2A15%29=105%2F135\"
\n" ); document.write( "A. \"23%2F27=23%2A5%2F%2827%2A5%29=115%2F135%3E103%2F135=7%2F9\" ,
\n" ); document.write( "so \"23%2F27\" is not between \"81%2F135=0.6\" and \"105%2F135=7%2F9\"
\n" ); document.write( "B. \"20%2F27=20%2A5%2F%2827%2A5%29=100%2F135\"
\n" ); document.write( "If there is only one right answer,
\n" ); document.write( "since \"81%2F135%3C100%2F135%3C105%2F135\" ,
\n" ); document.write( "\"0.6%3Chighlight%2820%2F27%29%3C7%2F9\"
\n" ); document.write( "
\n" ); document.write( "In fact the other two numbers are not between \"81%2F135=0.6\" and \"105%2F135=7%2F9\" :
\n" ); document.write( "C. \"14%2F27=14%2A5%2F%2827%2A5%29=70%2F135%3C81%2F135=0.6\" and
\n" ); document.write( "D. \"1%2F3=1%2A45%2F%283%2A45%29=45%2F135%3C81%2F135=0.6\"
\n" ); document.write( "
