      • Ratio compares part to part
    • Proportion
      • Direct Proportion
        • As one amount increases, another amount increases at the same rate

      • Proportions can be written as fractions or percentages
      • Inverse Proportion
        • When two quantities are in inverse proportion one increases, the other decreases in the same ratio
        • 1:8  = 2:?            Inverse Proportion
          • Steps:
            • 8=a Answer= n 1=b 2=c
              • c~b=n
    • Try These:
      • 1:8  = 2:?            Inverse Proportion
        • Steps:
          • 8=a Answer= n 1=b 2=c
            • c~b=n
