The explanation to the solution does not explain how one gets to the 1.25 gallons, etc. Can someone write a better explanation to this question?

9/(10+X) and 80/100 cross multiply and you have 900/80=10+x so 900÷80=11.25 now you have 11.25=10+x subtract 10 from both sides to get x by itself. Therefor you now have x=1.25....hope this help you
