Algebra.Com's Answer #437260 by KMST(5328)![]() ![]() You can put this solution on YOUR website! I believe the problem means that if you count by 4's for a while and then add 3, you get to the number, \n" ); document.write( "and if you count by 5's for a while and then add 3, you also get to the number. \n" ); document.write( "In both cases, before adding 3, you had arrived to a number that was a multiple of 4, and a multiple of 5. \n" ); document.write( "The smallest such number is \n" ); document.write( " \n" ); document.write( "That is the smallest number that you can arrive to by \n" ); document.write( "counting by 4's and adding 3, \n" ); document.write( "and also by counting by 5's and adding 3. \n" ); document.write( "The other larger such numbers are any multiple of \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "The next such number, \n" ); document.write( " \n" ); document.write( "So the number in the problem can be any of those 4 numbers: \n" ); document.write( "23 (the smallest), or 43, or 63, or 83. \n" ); document.write( " |
