Write the decimal number represented by the points A, B, C, D on the given number line.
Starting from 1, we move two steps to left and we reach point A. Therefore, point A is 0.8
Starting from 1, we move three steps to right and we reach point B. Therefore, point B is 1.3.
Starting from 2, we move two steps to right and we reach point C. Therefore, point C is 2.2.
Starting from 3, we move one step to left and we reach point D. Therefore, point D is 2.9.
