Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 3 liters of natural oil for every 4 liters of synthetic oil. In order to make 497 liters of Petrolyn oil, how many liters of natural oil are needed?

(3 / 7) * 497 = 213 liters of natural oil

As a double check:

(4 / 7) * 497 = 284 liters of synthetic oil needed

213 + 284 = 491 liters
