You need common denominators to solve this. So, what number do 2 and 4 share?
\n" ); document.write( "The number is \"4\"\r
\n" ); document.write( "\n" ); document.write( "\"1%2F2\" + \"%28-3%2F4%29\"\r
\n" ); document.write( "\n" ); document.write( "\"1%2F2\" = \"x%2F4\"
\n" ); document.write( "Since the \"2\" was multiplied by 2 to get 4, we do the same thing to the numerator, which is to multiply it by 2 as well.\r
\n" ); document.write( "\n" ); document.write( "\"1%2F2\" = \"2%2F4\"\r
\n" ); document.write( "\n" ); document.write( "Now, you can add the two fractions.\r
\n" ); document.write( "\n" ); document.write( "\"2%2F4\" + \"%28-3%2F4%29\"
\n" ); document.write( "answer \"-1%2F4\"
\n" ); document.write( "
\n" );
