To determine which number is located at point D, we first need to identify where each of the given numbers is positioned on the number line.
The numbers you've listed are:
- 0.8
- -1½ (which is -1.5 or -1.5)
- -1
- 2
- -1.99
Now we can place these on a number line (from left to right):
- -2 (not in your list, but left of -1.99)
- -1.99
- -1.5 (which corresponds to -1½)
- -1
- 0
- 0.8
- 1
- 2
Now let's assign each point a letter label as suggested, while also recognizing where point D is on the number line:
- Point A could correspond to -2
- Point B could correspond to -1.99
- Point C (not listed) could correspond to -1.5
- Point D could correspond to -1
- Point E could correspond to 0
- 1 and 2 seem straightforward and could follow naturally after point E
From the alignment, point D corresponds to -1.
Therefore, point D is located at -1.
