If you got 70% right, that means you got 30% WRONG.
\n" ); document.write( "You need to find 30% of 190. Solve the proportion:
\n" ); document.write( " $\"30%2F100+=+x%2F190\"$ (percent out of 100 = is over of)(30% OF 190 IS x)
\n" ); document.write( " $\"5700=100x\"$
\n" ); document.write( " $\"57+=+x\"$
\n" ); document.write( "----
\n" ); document.write( "Therefore you missed 57 questions.
\n" ); document.write( "----
\n" ); document.write( "You could also change 30% to a decimal and multiply by 190:
\n" ); document.write( " $\".3+%2A+190+=+57\"$ \n" ); document.write( "

\n" );
