Find the difference between the decimals represented by the points b and d on the given number line.
Consider the given number line.
Observe that:
The distance between 0 and 1; 1 and 2 each is divided into 10 equal parts.
So, each part represents a length of one-tenth or 0.1.
Now, count the number of parts from 0 to b.
There are 8 parts.
This means that the point b is 8 parts to the right of 0 or 8 tenths after 0.
Now, 0 and 8 tenths equals 0.8.
So, the decimal represented by the point b is 0.8.
Similarly, the decimal represented by the point d is 1.3.
Now, let's find the difference between the decimals represented by the points b and d.
Notice that point d is 5 parts ahead of point b.
Also, we know each part represents a length of one-tenth or 0.1.
So, 5 parts is 5 tenths or 0.5.
The difference between the decimals represented by the points b and d is 0.5.
