To determine which number is located farthest to the right on a number line, we need to compare the values of the given numbers:
- 0.8 (which is equal to \( \frac{8}{10} \) or \( \frac{4}{5} \))
- −1 1/2 (which is equal to -1.5)
- −1/4 (which is equal to -0.25)
- 2
- −1.99
Now let's list the numbers in order from smallest to largest:
- −1.99
- −1.5 (−1 1/2)
- −0.25 (−1/4)
- 0.8
- 2
From this order, we can see that 2 is the largest number and is located farthest to the right on the number line. Therefore, the number that is located farthest to the right is:
2.
