Hi  

25% of 20gal  |Note:  'of' indicates multiplication to solve

This can be done one of two two ways... using decimal or fraction 

.25(20)

0r

(1/4)20gal

Either way

25% of 20gal = 5gal



20gal- 5gal = 15gal

Need to take off 5 more gal to have half the water You started with.

Wish You the Best in your Studies.

since it is totally nonsensical.

    Edwin, how can I be sure that this "boy or girl" mistakenly omitted the word "HALF" ?


    May be, he (or she) omitted "one third" or "one fourth" ?  Or something else ?

    In this post, NEITHER the text NOR the context (which is absent) allow me to make a conjecture . . . 


    In this situation, it is not a tutor's concern/deal/function to guess.


    In this situation, the tutor's right reaction is to point a deficiency to the visitor.


    Guessing is not a correct reaction in this case.


    It is my point.  Other tutors may think differently.


    Regarding "to be nice", it is not my concern at this forum.


    At this forum, my goal and my job is to TEACH - those who is able to learn and wants do it.



    By the way, as you might know and might learn from many thousands of my posts,

Ikleyn, don't you think you're being a little too harsh on this boy or girl. All
he or she did wrong was to leave out the word "HALF".  Ewatrrr knew this was what
was meant, and she was nice as could be. You should learn to be nice yourself!
