Visualilse on the number line, upto 3 decimal places.

Step 1:

Here, the number lies between 5 and 6. First, draw the number line.

Step 2:

Divide the above part into 10 equal parts and make first point to the right of 5 as 5.1, the second 5.2 and so on.

Step 3:

Now, 5.28 lies between 5.2 and 5.3. So, by focusing on this portion, divide it into 10 equal parts and mark first point to the right of 5.2 as 5.21, the second 5.22 and so on.

Step 4:

Now, 5.282 lies between 5.28 and 5.29. So, focus on this portion and again divide it into 10 equal portions and mark first point to the right of 5.28 as 5.281 and the second one as 5.282.

The number 5.282 is the 2^nd mark in these subdivisions.
