Algebra.Com's Answer #110261 by mangopeeler07(462)![]() ![]() ![]() You can put this solution on YOUR website! You can simply put 84 over 120 and divide:\r \n" ); document.write( "\n" ); document.write( "84/120=.7000\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now move the decimal over twice to the right to get the percent: \n" ); document.write( "70.00% \n" ); document.write( "-------------------------------------------------------------------------------- \n" ); document.write( "Or you can cross multiply with two fractions:\r \n" ); document.write( "\n" ); document.write( "84/120=x/100\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The x is over 100 because you want the percent, not the decimal. This proportion is literally saying, \"84 is to 120 as x is to 100\". You can also do:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "120/84=100/x which is literally saying, \"120 is to 84 as 100 is to x\". As long as you are consistent, it doesn't matter.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Once you have: \n" ); document.write( "84/120=x/100,\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "cross multiply. \n" ); document.write( "84(100)=120(x)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Simplify \n" ); document.write( "8400=120x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Divide both sides by 120 \n" ); document.write( "70=x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so 70%. \n" ); document.write( "-------------------------------------------------------------------------------- \n" ); document.write( "It doesn't matter which way you do it, so whichever is easier for you to do, by all means, do it that way. I hope I've helped you! \n" ); document.write( " |
