Algebra.Com's Answer #299449 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! Let x = the smaller number \n" ); document.write( "Then the larger number = 5x \n" ); document.write( "Given: the sum of their reciprocals = 3/5 \n" ); document.write( "In equation form this is: \n" ); document.write( "1/x + 1/(5x) = 3/5 \n" ); document.write( "Multiply through by x: \n" ); document.write( "1 + 1/5 = (3/5)x -> (3/5)x = 6/5 -> x = (5/3)(6/5) = 2 \n" ); document.write( "So the other number = 5*2 = 10 \n" ); document.write( "Ans: 2, 10 \n" ); document.write( " |
