You can put this solution on YOUR website!
your expression is:
\n" ); document.write( "(11 1/6) + (2 7/9) - 4
\n" ); document.write( "this is equivalent to:
\n" ); document.write( "(11 + 1/6) + (2 + 7/9) - 4
\n" ); document.write( "this is equivalent to:
\n" ); document.write( "11 + (1/6) + 2 + (7/9) - 4
\n" ); document.write( "combine like terms to get:
\n" ); document.write( "9 + 1/6 + 7/9
\n" ); document.write( "the + 11 and the + 2 and the - 4 were common (they were all integers) and so they were combined together to equal 9.
\n" ); document.write( "in order to add fractions, you have to get a common denominator for them.
\n" ); document.write( "the least common denominator for (1/6) and (7/9) is 18.
\n" ); document.write( "multiply (1/6) by (3/3) and multiply (7/9) by (2/2) to get:
\n" ); document.write( "9 + (3/18) + (14/18)
\n" ); document.write( "combine the fractions together now that they have a common denominator to get:
\n" ); document.write( "9 + (17/18)
\n" ); document.write( "that's your answer in mixed fraction form.
\n" ); document.write( " \n" ); document.write( "

\n" );
