The following exercises present you with fairly straightforward ratio and proportion situations.   A. If the Dow Jones Industrial Average in the stock market began the day at 12,000 and lost 700 points, how much would a proportional fall be if the stock market began the day at 1,000? Estimate the answer and explain how you obtained the estimate.   Determine the actual answer. (Round your answer to the nearest whole number.)   Explain whether the actual answer is, itself, actually exact or an approximation.   (b) If the stock market was at 2,700 and rose 45 points, how much would a proportional rise be if the stock market began the day at 10,000? Estimate the answer and explain how you obtained the estimate.   Determine the actual answer. (Round your answer to the nearest whole number.)     Explain whether the actual answer is, itself, actually exact or an approximation.
