We need to add an amount to yellow marbles to make it so that the ratio is 2:1.\r \n" ); document.write( "\n" ); document.write( "We can set it up like this. Let x be the amount that we add to the yellow marbles.\r \n" ); document.write( "\n" ); document.write( "Then (8+x)/6 = 2/1\r \n" ); document.write( "\n" ); document.write( "So 8+x = 12 by cross multiplication.\r \n" ); document.write( "\n" ); document.write( "x = 4\r \n" ); document.write( "\n" ); document.write( "So we can add 4 yellow marbles to get a ratio of 2:1. \n" ); document.write( " |
