Hi,

If the ratio of Republicans to Democrats in a district is 4 to 9,

Let 4x and 9x represent the number of Republicans and Democrats respectively

a total of 2210 Republicans and Democrats in that district

  4x+%2B+9x+=+2210

    13x = 2200

      x = 170

Number Republicans  4x  Or  680

Number Democrats    9x  Or 1530



total Republicans and Democrats  2210
