2.

To do the comparison, we'll use the following temperatures:

Day 1: 5°F

Day 2 : 1.5°F

Comparison of Day 1 and Day 2:

1.5F

or

5F>1.5F

Comparison of days with absolute value:

1.5F

or

5F>1.5F

3.

The temperature that's the closest to 0 during the week is -0.5°F. Using absolute value, we can see that the distance from 0°F to -0.5°F is the smallest of all the temperature measurements.

4.

The temperature that's the farthest to 0 during the week is 5°F. Using absolute value, we can see that the distance from 0°F to 5°F is the biggest of all the temperature measurements.

5.

The coldest temperature is -4°F. This is the value that is farthest to the left of 0°F on the number line.

6.

The warmest temperature is 5°F. This is the value that is farthest to the right of 0°F on the number line.
