Scaled solar system ratio help

  1. Mar 2, 2009 #1
    1. The problem statement, all variables and given/known data
    In a scaled solar system: Earth's radius is 6,375 km, it's scaled radius is 12.75 cm. Neptune has a radius of 24,766 km; using centimeters, what would the scaled radius of Neptune be??


    2. Relevant equations
    I'm not sure what to put here; I put down what I tried below.


    3. The attempt at a solution

    12.75 cm
    ________ ......... = ........... ______________
    637,500,000 cm .............. 2,476,600,000 cm

    x= 49.532 cm


    Did I do this right?!?!
