You can put this solution on YOUR website!
You have a choice of trying the solution multistep or putting it altogether in a single proportion.
Area to volume, or volume to area, your choice.

1%2F300=v%2F%284%2A200%29 and v is used as the number of gallons of this paint to use.
In case v is not a whole number, round UPward.

Note, I chose gallons to area, because now you simply multiply left member and right member by 4%2A200 to solve for v.



You should find v=8%2F3, not a whole number. Need 3 gallons ( because 2%262%2F3 is not a whole number ).
