You can put this solution on YOUR website!
For problems like this, I like to write the mixed numbers as improper fractions, while remembering that numbers like -2 3/4 are (-1)(2 + 3/4):\r
\n" ); document.write( "\n" ); document.write( "


\n" );
document.write( "-2 3/4 - (-3 5/6) =  -11/4 + 23/6 \r
\n" );
document.write( "\n" );
document.write( "and then you need to put them over a common denominator (in this case, 12):\r
\n" );
document.write( "\n" );
document.write( " =  -33/12 + 46/12 
\n" );
document.write( " =  13/12
\n" );
document.write( " =   1 1/12 
\n" );
document.write( "or about 1.0833333 
\n" );
document.write( " \n" );
document.write( "

\n" );
