Decimal Number Lines Part 1
Consider the number line given below.
Let's find the decimal represented by the point r.
Observe that:
The distance between 0 and 1 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 r.
There are 8 parts.
This means that the point r 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 r is 0.8.
