\n" ); document.write( "The way I read it is that 45% of the class passed
\n" ); document.write( "the 1st test, and some of that 45% also passed the 2nd test.
\n" ); document.write( "The 30% that passed both tests is included within the 45% that
\n" ); document.write( "passed the 1st test.
\n" ); document.write( "So the problem is asking \"30 is what percent of 45?\"
\n" ); document.write( "\"+x%2F100+=+30%2F45+\"
\n" ); document.write( "\"+x+%2F100+=+2%2F3+\"
\n" ); document.write( "\"+3x+=+200+\"
\n" ); document.write( "\"+x+=+66.67+\"
\n" ); document.write( "66.67% of those who passed 1st test also passed 2nd test
