well im not gonna do it for you but here is an example just like your just different numbers are plug in

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 6 liters of natural oil for every 5 liters of synthetic oil. In order to make  847liters of Petrolyn oil, how many liters of natural oil are needed?

If you have 6x liters of natural oil, then you have 5x liters of synthetic oil. (It doesn't matter what x here stand for). Thus, you have 6x+5x=11x liters of Petrolyn motor oil.
If we have 847 liters of Petrolyn oil, then 11x=847 which means x=77 and 6x=462 liters of natural oil is needed.
