Answer 1

To solve the subtraction problem expressed by the number line, we start at \( \frac{5}{6} \) and move three tick marks to the left.

Each tick mark represents a movement of \( \frac{1}{6} \).

Starting at \( \frac{5}{6} \):

1. Move one tick to the left: \( \frac{5}{6} - \frac{1}{6} = \frac{4}{6} \)
2. Move a second tick to the left: \( \frac{4}{6} - \frac{1}{6} = \frac{3}{6} \)
3. Move a third tick to the left: \( \frac{3}{6} - \frac{1}{6} = \frac{2}{6} \)

Thus, after moving three tick marks to the left from \( \frac{5}{6} \), we arrive at \( \frac{2}{6} \).

The answer is: 2/6
