When construction is completed in Daisy Hill Subdivision there will be a total of 50 homes. What is the approximate ratio of new homes currently completed to new homes currently under construction?
选项 A、1:2
B、13:21
C、5:8
D、21:25
E、4:3
答案B
解析 The correct answer is B. According to the graph, 26% of the homes have been completed, which means that 50(0.26)= 13 homes have been completed. The graph shows that 42% of the homes are currently under construction: 50(0.42)= 21. Therefore, the ratio is 13:21.
