The best statement that explains Hanna's thinking is:
Hanna is not correct. The fraction One-fourth is equal to StartFraction 2 Over 8 EndFraction, so you can graph it on the second tick mark to the right of zero.
This is because on a number line divided into eight equal parts between 0 and 1, one-fourth (1/4) corresponds to the point that is two ticks to the right of zero (since 1/4 is equal to 2/8).
