Question

. Which could be a value for n?

Answer 1

Answer:

A. $-\frac{1}{2}$

Step-by-step explanation:

Each mark represent 0.1 unit, so if you count from 0 to $n$ you get 0.5 that is exactly the same that $-\frac{1}{2}$ (for convention the left of the 0 is taken as negative and the right as positive).
