Gina measured the amount of water her friends drink each day in gallons. The line plot shows the measurements.
vova2212 [387]

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:

Least = 8\frac 28

Greatest = 8\frac 68

<h3>Calculating the difference</h3>

The difference (d) is then calculated as:

d =Greatest -Least

So, we have:

d =8\frac 68 -8\frac 28

Subtract the common terms (8)

d =\frac 68 -\frac 28

Take LCM

d =\frac {6-2}8

d =\frac {4}8

Reduce the fraction

d =\frac {1}2

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