Answer:
d. It is the same distance from zero as the number she tells you
Step-by-step explanation:
Case 1: Let Shanika thought a positive rational number
Let the number that Shanika thought be c.
Then, the distance of it from zero = |c - 0| = c.
But, the number she told = -c
The distance of -c from zero = |0--(-c)| = c
Case 2: Let Shanika thought a negative rational number
Let the number that Shanika thought be -c (c > 0).
Then, the distance of it from zero = |0--(-c)| = c.
But, the number she told = c
The distance of -c from zero = |c - 0| = c
In both cases, the number she thought is the same distance from zero as the number she tells us
