Here's how to find the number the arrow points to on the number line:

Identify the integers surrounding the arrow.
The arrow is located between the integers $-3$ and $-2$ .
Determine the value of each small tick mark.
Between any two consecutive integers (e.g., $-3$ and $-2$ ), there are 10 small tick marks. This means each small tick mark represents 0.1 units.
Count the tick marks from the nearest integer.
Starting from $-3$ and moving to the right (towards $-2$ ), the arrow points to the second tick mark.
So, the value is $-3 + 0.1 + 0.1 = -3 + 0.2 = -2.8$ .

Alternatively, starting from $-2$ and moving to the left (towards $-3$ ), the arrow points to the eighth tick mark.
So, the value is $-2 - 0.1 - 0.1 - 0.1 - 0.1 - 0.1 - 0.1 - 0.1 - 0.1 = -2 - 0.8 = -2.8$ .

The number the arrow points to is:
$\mathbf{-2.8}$
