convert them to the same denominator
\n" ); document.write( "2/3 +3/4
\n" ); document.write( "multiply 3*4=12
\n" ); document.write( "the first fraction is 2/3
\n" ); document.write( "12/3=4
\n" ); document.write( "so multiply both numeration and denominator by 4 that is by 4/4 which is really 1 in disguise
\n" ); document.write( "4/4*2/3=8/12
\n" ); document.write( "next fraction
\n" ); document.write( "12/4=3
\n" ); document.write( "multiply 3/4*3/3=9/12
\n" ); document.write( "so now we have 8/12+9/12
\n" ); document.write( "add 8+9=17\r
\n" ); document.write( "\n" ); document.write( "17/12
\n" ); document.write( "now reduce the improper fraction to a mixed number
\n" ); document.write( "17/12= 1 5/12 done
\n" ); document.write( "so we did
\n" ); document.write( "2/3+3/4
\n" ); document.write( "3*4=12
\n" ); document.write( "2/3*4/4+3/4*3/3
\n" ); document.write( "8/12+9/12
\n" ); document.write( "17/12
\n" ); document.write( "1 5/12\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
