Line plots are used to represent data using lines and dots
The difference between the greatest amount of water and the least is 1/2
From the line plot (see attachment), we have the following parameters:


<h3>Calculating the difference</h3>
The difference (d) is then calculated as:

So, we have:

Subtract the common terms (8)

Take LCM


Reduce the fraction

Hence, the difference between the greatest amount of water and the least is 1/2
