A. 55.6
B. 55.8
C. 56.2
D. 56.8
That's Correct!
It's Wrong!

Consider the given number line.

Observe that:

The distance between 55 and 56 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 55 to y.

There are 8 parts.

This means that the point y is 8 parts to the right of 55 or 8 tenths after 55.

Now, 55 and 8 tenths equals 55.8.

So, the decimal represented by the point y is 55.8.
