1/4 + 1/3 + 1/6 = ?
\n" ); document.write( "The common denominator is 12.
\n" ); document.write( "1/4 = 3/12
\n" ); document.write( "1/3 = 4/12
\n" ); document.write( "1/6 = 2/12
\n" ); document.write( ".
\n" ); document.write( "9/12 have been sold = 75%.
\n" ); document.write( ".
\n" ); document.write( "So 25% of the pies have not been sold.
\n" ); document.write( "25% of 20 = 1/4 * 20 = 5
\n" ); document.write( ".
\n" ); document.write( "The baker still has 5 pies.
\n" ); document.write( ".
\n" ); document.write( "But there is a problem with this problem statement:
\n" ); document.write( "You cannot buy 1/3 of 20 pies unless the baker lets you buy 6 2/3 pies.
\n" ); document.write( "Similarly, you cannot buy 1/6 of 20 pies unless the baker lets you buy 3 1/3 pies.
\n" ); document.write( "The math works, but I don't know any bakers who sell partial pies.
\n" ); document.write( ".
\n" ); document.write( "Done.
\n" ); document.write( "
\n" );
