Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil. If 255 liters of natural oil are used, how many liters of Petrolyn oil will be made?

153 liters of Petrolyn oil

Step-by-step explanation:

This is a proportion to set this up you do the following:

Nat/Syn = Nat/Syn; 5/3 = 255/Syn

Then you solve this equation by cross multiplication.

(255*3) / 5 = Syn

153 = Synthetic (Petrolyn oil)
