See a solution process below:

Explanation:

First, we can rewrite the percentage lost as: 6.25%

We can now find what 6.25% of 64 is. "Percent" or "%" means "out of 100" or "per 100", Therefore 6.25% can be written as #6.25/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number of gallons we are looking for "g".

Putting this altogether we can write this equation and solve for #g# while keeping the equation balanced:

#g = 6.25/100 xx 64#

#g = 400/100#

#g = 4#

4 gallons of water were lost.

To find how much is left we can subtract:

#64 - 4 = 60#

There are #color(red)(60)# gallons of water remaining.
