In other words, 3/10 are red and 7/10 are blue, soooo if there are 250 marbles, 3/10 are red and 7/10 are blue. \n" ); document.write( "3/10(250)=75 are red and \n" ); document.write( "7/10(250)=175 are blue and the ratio of red to blue is 75/175=3/7\r \n" ); document.write( "\n" ); document.write( "Hope this helps--ptaylor \n" ); document.write( " |
