The following numbers are shown on a number line 0.8, -1 1/2, -1/4, 2, -1.99 which number is located farthest to the right

To determine which number is located farthest to the right, we need to find the largest value among the given numbers on the number line.

0.8 is located between 0 and 1, so it is not the farthest to the right.
-1 1/2 is located between -2 and -1, so it is not the farthest to the right.
-1/4 is located between -1/2 and 0, so it is not the farthest to the right.
2 is located between 1 and 3, so it is the farthest to the right.
-1.99 is located between -2 and -1, so it is not the farthest to the right.

Therefore, the number located farthest to the right is 2.

To determine which number is located farthest to the right on a number line, you need to find the number with the greatest value.

The numbers given are:
0.8,
-1 1/2 = -1.5,
-1/4,
2, and
-1.99.

To compare these numbers, let's convert the mixed number -1 1/2 to a decimal:
-1 1/2 = -1 - 1/2 = -1 - 0.5 = -1.5.

Now, we have the following decimals:
0.8,
-1.5,
-1/4 = -0.25,
2, and
-1.99.

Comparing these decimals, we find that 2 is the largest. Therefore, the number 2 is located farthest to the right on the number line.
