d=5. 03894 and |d| is the decimal expression for d rounded to the nearest thousandth.
Column A Column B
The number of decimal places where d and |d| differ 4
选项
A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案
B
解析
d=5.03894且|d|是d四舍五入到千分位的小数表达(decimal expression)。
解:本题的正确答案是(B)。“to the nearest”是汉语中“四舍五入”最常见的表达方式。所以|d|=5.039。解答该题的关键在于精确理解比较左项的意义,注意:Where引导的定语从句修饰的是places,即左项意义为d和|d|的小数位置上的数不相同的数目。d和|d|在千分位,万分位,十万分位3个位置上的数都不同。
