The ratio of boys to girls is approx. 7:5. So let n be the proportions of students. Then:
\n" ); document.write( "7n+5n=850
\n" ); document.write( "12n=850
\n" ); document.write( "n=70.83
\n" ); document.write( "There are 5n girls, or about 354 girls in the school. ☺☺☺☺
\n" ); document.write( "
\n" );
