C. 0.7
D. 7.0
That's Correct!
It's Wrong!

Consider the given number line.

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 3 parts.

This means that the point r is 3 parts to the right of 0 or 3 tenths after 0.

Now, 0 and 3 tenths equals 0.3.

So, the decimal represented by the point r is 0.3.
