A. 4.0
B. 4.1
C. 4.2
D. 4.3
That's Correct!
It's Wrong!

Consider the given number line.

The length between 3 and 4; 4 and 5 is 1 each.

Observe that:

The distance between 4 and 5 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 4 to d.

There is 1 part.

This means that the point d is 1 part to the right of 4 or 1 tenth after 4.

Now, 4 and 1 tenth equals 4.1.

So, the decimal represented by the point d is 4.1.
