Algebra.Com's Answer #295592 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! We can write 500/499 as 1/(499/500). \n" ); document.write( "499/500 = (500 - 1)/500 = 1 - 1/500. 1/500 = 0.002 -> 499/500 = 1 - 0.002. \n" ); document.write( "We need to solve 1/(1-0.002). \n" ); document.write( "Multiply numerator and denominator by 1 + 0.002 -> (1)(1+0.002)/(1-0.002)(1+0.002) \n" ); document.write( "The denominator -> 1 since the 0.002*-0.002 term is very small. \n" ); document.write( "So the answer is approximately 1.002 \n" ); document.write( " |
