1.how many two-digit primes are there whose units digit is more than its tens digit ?
\n" ); document.write( "
\r\n" );
document.write( "Here they all are.  You count them:\r\n" );
document.write( "13, 17, 19, 23, 29, 37, 47, 59, 67, 79, 89\r\n" );
document.write( "

\n" ); document.write( "2.how many four-digit numbers are multiples of 15 ?
\n" ); document.write( "The smallest 4-digit number is 1000, divide 1000 by 15, get 66.666...
\n" ); document.write( "So take the next integer 67. Multiply it by 15 and get 1005, which
\n" ); document.write( "is the smallest 4-digit multiple of 15
\n" ); document.write( "
\r\n" );
document.write( "The largest 4-digit number is 9999, divide 9999 by 15, get 666.6\r\n" );
document.write( "So take the largesr integer less that that which is 666.  Multiply \r\n" );
document.write( "666 by 15 and get 9990, which is the largest 4-digit multiple of 15.\r\n" );
document.write( "\r\n" );
document.write( "So the numbers we are looking for are these:\r\n" );
document.write( "\r\n" );
document.write( "67x15, 68x15, ... , 666x15, inclusive\r\n" );
document.write( "\r\n" );
document.write( "There's the same number of them as there are integers from 66 to 666\r\n" );
document.write( "\r\n" );
document.write( "There are 666 integers from 1 to 666.\r\n" );
document.write( "We need to subtract from that the number of integers from 1 to 66\r\n" );
document.write( "666-66 = 600\r\n" );
document.write( "\r\n" );
document.write( "So there are 600 4-digit multiples of 15.\r\n" );
document.write( "------------------\r\n" );
document.write( "

\n" ); document.write( "the product of two positive integers is 4028 and their gcf is 2.
\n" ); document.write( "
\r\n" );
document.write( "4028 = 2x2014, the only factor of 2 (other than 1) is 2. So the\r\n" );
document.write( "2 positive integers are 2 and 2014.\r\n" );
document.write( "

\n" ); document.write( "what is their lcm
\n" ); document.write( "
\r\n" );
document.write( "Their lcm is 2014\r\n" );
document.write( "------------------\r\n" );
document.write( "That's all for now.  You are only allowed 2 questions and I answered 3.\r\n" );
