Answer:

The total change in the water level is [tex]-\frac{33}{28}[/tex]

Step-by-step explanation:

In order to get the total change in something is to add all the numbers together. So, over that three month period, you add -1 3/4-1/28-15/28. SInce you are adding fractions, it helps to have all the denominators the same. Change -1 3/4 into -49/28. (all I did was turn the fraction into an improper fraction then did  [tex]\frac{7*7}{7*4}=\frac{49}{28}[/tex] )

Now that we have all the same denominators, just add them/combine them.

[tex]-\frac{49}{28} -\frac{1}{28} -\frac{15}{28}[/tex] = [tex]-\frac{33}{28}[/tex]
