To determine which number is located farthest to the right on the number line, we can compare the given numbers: 0.8, −112, −14, 2, and −1.99.
Among these numbers, the only positive number is 2. All the other numbers (−112, −14, −1.99, and 0.8) are either negative or less than 2.
Thus, the number that is located farthest to the right on the number line is 2.
