A. 1.5
B. 1.7
C. 1.9
D. 1.3
That's Correct!
It's Wrong!

Consider the given number line.

Observe that:

The distance between 1 and 2 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 1 to d.

There are 9 parts.

This means that the point d is 9 parts to the right of 1 or 9 tenths after 1.

Now, 1 and 9 tenths equals 1.9.

So, the decimal represented by the point d is 1.9.
