Answer:
Total 495 liters of natural oil are needed.
Explanation:
It is given that 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.
It means the ratio of natural oil and synthetic oil is
Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.
It means the ratio of natural oil and synthetic oil is
Equate both ratios,
![\frac{x}{792}=\frac{5}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B792%7D%3D%5Cfrac%7B5%7D%7B8%7D)
On cross multiplication we get
![8\times x=5\times 792](https://tex.z-dn.net/?f=8%5Ctimes%20x%3D5%5Ctimes%20792)
![8x=3960](https://tex.z-dn.net/?f=8x%3D3960)
Divide both sides by 8.
![x=\frac{3960}{8}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3960%7D%7B8%7D)
![x=495](https://tex.z-dn.net/?f=x%3D495)
Therefore total 495 liters of natural oil are needed.
