\"n+%2B+3%2F4\"
\n" ); document.write( "\"n+=+1%2F3\"
\n" ); document.write( "The least common multiple is \"3%2A4+=+12\"
\n" ); document.write( "If you have a computer, helpwithfractions.com is good
\n" ); document.write( "You can multiply the top and bottom of any fraction
\n" ); document.write( "by the same number without changing the fraction
\n" ); document.write( "\"n+=+1%2F3\"
\n" ); document.write( "\"n+=+%284%2F4%29%2A%281%2F3%29\"
\n" ); document.write( "\"n+=+4%2F12\"
\n" ); document.write( "This is the same as
\n" ); document.write( "\"n+=+1%2A%281%2F3%29\" and doesn't change the fraction
\n" ); document.write( "Also, \"3%2F4+=+%283%2F3%29%2A%283%2F4%29\"
\n" ); document.write( "\"3%2F4+=+9%2F12\" again, I have not changed the fraction
\n" ); document.write( "\"n+%2B+3%2F4+=+n+%2B+9%2F12\"
\n" ); document.write( "and I already determined
\n" ); document.write( "\"n+=+4%2F12\"
\n" ); document.write( "\"4%2F12+%2B+9%2F12+=+13%2F12\" or 1 1/12 answer
\n" ); document.write( "----------------------------
\n" ); document.write( "And n = 1 3/4
\n" ); document.write( "Note that \"1+=+4%2F4\", so I can rewrite it as
\n" ); document.write( "1 3/4 = \"4%2F4+%2B+3%2F4+=+7%2F4\"
\n" ); document.write( "\"n+%2B+3%2F4+=+7%2F4+%2B+3%2F4\"
\n" ); document.write( "\"7%2F4+%2B+3%2F4+=+10%2F4\", or 2 1/2 answer
\n" ); document.write( "I hope this helps you to proceed
