Algebra.Com's Answer #870 by longjonsilver(2297)![]() ![]() You can put this solution on YOUR website! 1. n=2 - by cross multiplying and then reducing the fraction left there (18/9).\r \n" ); document.write( "\n" ); document.write( "2. percentage...PER CENT....out of 100!!!! \n" ); document.write( "so...37.5% is 37.5/100 or if you like...75/200..now simplify it...divide everything by 25...3/8. Voila :-)\r \n" ); document.write( "\n" ); document.write( "20% of x is 50 ... of means multiply \n" ); document.write( "(20/100)x = 50\r \n" ); document.write( "\n" ); document.write( "Re-arranging gives x=250\r \n" ); document.write( "\n" ); document.write( "Jon \n" ); document.write( " |
