Answer:
The pink dot will go one space to the left of -1.
The green dot will go one space to the right of 0.
The blue dot will go one space to the right of -1.
The yellow dot will go two spaces to the left of 0.
Explanation:
Each of the small lines in between the whole numbers represents quarters.
Pink goes one line to the left of -1, because that is -1 1/4, also known as -1.25.
Green goes one line to the right of 0 because that is 1/4, or 0.25.
Blue goes one line to the right of -1 (or three lines left of 0) because that is -3/4 or -0.75.
Yellow goes two lines to the left of 0 (or one line right of blue dot), because that is -0.5.
