A. 2.3
B. 2.1
C. 1.9
D. 2.7
That's Correct!
It's Wrong!

Consider the given number line.

Observe that:

The distance between 2 and 3 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 2 to y.

There are 3 parts.

This means that the point y is 3 parts to the right of 2 or 3 tenths after 2.

Now, 2 and 3 tenths equals 2.3.

So, the decimal represented by the point y is 2.3.
