问题 [br] What is the ratio of the number of people on the Slim Fast diet in 1995 to the number of people on the Mediterranean diet in 2000?
选项 A、3/28
B、1/4
C、1/3
D、9/28
E、27/98
答案 D
解析 The correct answer is D. In 1995, 3% of 135 million people were on the Slim Fast diet: 0.03 × 135=4.05. In 2000, 6% of 210 million people were on the Mediterranean diet: 0.06×210 = 12.6. So the ratio is 4.05 : 12.6, or 405: 1,260. This reduces to 9:28 or 9/28
