If n denotes a number to the left of 0 on the number line such that the square of n is less than 1/100, then the reciprocal of n must be
A. less than -10
B. between -1 and -1/10
C. between -1/10 and 0
D. between 0 and -1/10
E. greater than 10
Let n = -1/20.
This works because (-1/20)² = 1/400, which is less than 1/100.
In this case, the reciprocal of n = -20.
Only answer choice
A works:
-20 is less than -10.
The correct answer is
A.
