Alright so, first you would want to figure out how many inches are in one centimeter. You would do this by taking 5.08 divided by 2. You divide it by 2 since 5.08 centimeters equals 2 inches. The answer to that is 2.54. So 2.54 centimeters equals 1 inch. Then you would take 2.54 and multiply it by 11 (since you need 11 inches). The answer to that is 27.94. Therefore Kate has 27.94 inches of ribbon. Also, your answer for question 10 would be C.) 1,800. Hope that helps!
