90 students in the school.
\n" ); document.write( "each student attends 4 classes.
\n" ); document.write( "each class has 15 students and 1 teacher.
\n" ); document.write( "each teacher teaches 3 classes.
\n" ); document.write( "there is 1 teacher per class.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since each class contains 15 students, then 90 / 15 = a minimum of 6 classes assuming each student only had 1 class.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since each student has 4 classes, then they need 4 * 6 = a minimum of 24 classes to accommodate them.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since each teacher teaches 3 classes, then they need a minimum of 24 / 3 = 8 teachers to teach those classes.\r
