Answer 2

Coordinating the Ray with a Unit Segment of Length 8 Cells

To coordinate the ray with a unit segment of length 8 cells, we need to determine the positions of the points on the ray that correspond to the fractions 1/8, 3/4, 1 1/2, and 2 1/4.

Let's break down the problem step by step:

1/8: To find the position on the ray that corresponds to 1/8, we divide the length of the ray (8 cells) by 8. This gives us 1 cell. Therefore, the position on the ray that corresponds to 1/8 is at the first cell.

3/4: To find the position on the ray that corresponds to 3/4, we multiply the length of the ray (8 cells) by 3/4. This gives us 6 cells. Therefore, the position on the ray that corresponds to 3/4 is at the sixth cell.

1 1/2: To find the position on the ray that corresponds to 1 1/2, we add 1 to the length of the ray (8 cells) and then multiply by 1/2. This gives us 9 cells. Therefore, the position on the ray that corresponds to 1 1/2 is at the ninth cell.

2 1/4: To find the position on the ray that corresponds to 2 1/4, we add 2 to the length of the ray (8 cells) and then multiply by 1/4. This gives us 2.5 cells. Since we cannot have a fraction of a cell, we round it to the nearest whole number. Therefore, the position on the ray that corresponds to 2 1/4 is at the third cell.

In summary, the positions on the ray that correspond to the fractions 1/8, 3/4, 1 1/2, and 2 1/4 are as follows: - 1/8: First cell - 3/4: Sixth cell - 1 1/2: Ninth cell - 2 1/4: Third cell.

Please note that the above calculations are based on the assumption that the ray is evenly divided into cells and that the length of the ray is 8 cells.
