Let \"x\" = total study time
\n" ); document.write( "So,
\n" ); document.write( " $\"%281%2F3%29x\"$ = Math homework
\n" ); document.write( " $\"%282%2F7%29x\"$ = Preparing history exam
\n" ); document.write( "Adding the two we'll get the time allocated for these right?
\n" ); document.write( "= $\"%281%2F3%29x+%2B+%282%2F7%29x\"$
\n" ); document.write( "= $\"%287x%2B6x%29%2F21\"$
\n" ); document.write( "= $\"+highlight%28%2813%2F21%29x%29\"$ -------- time allocated for Math & history
\n" ); document.write( "So total study time remaining,
\n" ); document.write( "= $\"x-+%2813%2F21%29x\"$
\n" ); document.write( "= $\"x%281-13%2F21%29\"$
\n" ); document.write( "= $\"highlight%28%288%2F21%29x%29\"$ ----------- time remainig to study
\n" ); document.write( "So if he has total 60 minutes allocated(just an example) for the whole study,
\n" ); document.write( "= $\"%288%2F21%29%2860%29\"$
\n" ); document.write( "= 22.86 minutes remains
\n" ); document.write( "
