Answer 2

Answer:

The 2nd number line shows correcty for 0.8+0.3

Step-by-step Explanation:

We know that when we add 0.8 and 0.3 we get 1.1.

In a number line, when we go from left to right the number increases.

Here in the number line shown at 2nd place, we can see that first the step goes from 0 to 0.8 which is 0.8 units and then 0.3 units from 0.8 to 1.1.

Hence it is correct for 0.8+0.3

Comparing other situations:

~1st case

In the first case it is going from right to left and the unit value is decreasing. So if is not applicable for addition values.

~3rd case

In the third case the number line goes 0.8 units from left to right and then 0.3 units from right to left this case will be capable for case 0.8-0.3 as the unit value is decreasing.

~4th case

In the last case we can see that the values substitution in number line starts from 0.3 goes to 1.1 and moving from right to left. Here, this case will also be not capable, as unit length is always measured from 0. We can't put values from central values.
