If abc ≠ 0, is ~$\frac{\frac{a}{b}}{c}=\frac{a}{\frac{b}{c}}$~?

(1) a = 1

(2) c = 1

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

EACH statement ALONE is sufficient.

Statements (1) and (2) TOGETHER are NOT sufficient.

##### 考题讲解

（1）    条件1仅有a的值，无法得到判断题目。

（2）  条件2中c=1，满足~$c^2=1$~，能够进行判断。
