To determine which number is located farthest to the right on a number line, we can convert all the numbers to decimal form:
- \(0.8\) is already in decimal form.
- \(-1 \frac{1}{2}\) or \(-1.5\) in decimal form.
- \(-\frac{1}{4} = -0.25\) in decimal form.
- \(2\) is already in decimal form.
- \(-1.99\) is also already in decimal form.
Now, let's list these numbers in decimal form:
- \(0.8\)
- \(-1.5\)
- \(-0.25\)
- \(2\)
- \(-1.99\)
Now we can compare them:
- The least negative number is \(-0.25\), which is greater than all the negative numbers.
- Next is \(0.8\).
- And the largest number is \(2\).
Thus, the number located farthest to the right on the number line is \(2\).
