請問一下 有點點不了解這題目....請各位大大幫忙解釋一下
If n is a positive integer that is less than 10, what is the value of n?

(1)n is the tenth digit in the decimal representation of 1/n.
(2)n is the hundredth digit in the decimal representation of 1/n.

為何是A壓.....

根據題目n可能的數為1,2,3,4,5,6,7,8,9
由(1)n只能為3
由(2)n可能為3,6
所以答案為A
