Bot the following numbers are shown on the number line: -1.8, 0.8, 3.1, -1.2, 2 3/4. Which number is represented by point B? pick one of these answers. -1.8 0.8 -1.2 2 3/4

The number represented by point B is -1.2.

To determine which number is represented by point B on the number line, we need to compare the given numbers to their corresponding positions on the number line.

Given the numbers -1.8, 0.8, 3.1, -1.2, and 2 3/4, we can eliminate 3.1 as it is not one of the given answer choices.

To compare the remaining numbers, let's start by ordering them from least to greatest:

-1.8, -1.2, 0.8, 2 3/4

Now, we can see that -1.8 is to the left of -1.2, -1.2 is to the left of 0.8, and 0.8 is to the left of 2 3/4.

Since point B lies between -1.2 and 0.8 on the number line, the number represented by point B is -1.2.

Therefore, the correct answer is -1.2.
