Algebra.Com's Answer #465843 by MathLover1(20850)![]() ![]() You can put this solution on YOUR website! \r \n" ); document.write( "\n" ); document.write( "for number to be divisible by 45 it should be divisible by both 5 and 9 \r \n" ); document.write( "\n" ); document.write( "as you can see, last digit is \n" ); document.write( "for number to be divisible by \n" ); document.write( "\n" ); document.write( "so, answer is: the remainder is \n" ); document.write( " \n" ); document.write( "but to be sure, check the divisibility by \n" ); document.write( "\n" ); document.write( "in order to do that, we need to find the sum of the digits of N=12345678.........424344:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "or, faster this way:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "so sum of digits is \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "since \n" ); document.write( "\n" ); document.write( " dividing the number by \n" ); document.write( "\n" ); document.write( "so, your answer is: the remainder is \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
