$\"20=5%2A4\"$ so 20 is the 4th multiple of 5 (the first three being 5, 10, and 15)
\n" ); document.write( " $\"100=5%2A20\"$ so 100 is the 20th multiple of 5
\n" ); document.write( "In between are:
\n" ); document.write( " $\"5%2A5=25\"$ , $\"5%2A6=30\"$ and so on up to $\"5%2A19=95\"$
\n" ); document.write( "If you count 20 and 100, there are 17 of the first 20 multiples of 5 between 20 and 100.
\n" ); document.write( "If 20 and 100 are not included, then there are 15. \n" ); document.write( "

\n" );
