Question 991490: 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. In order to make 440 liters of Petrolyn oil, how many liters of natural oil are needed?
Answer by Cromlix(4381)   (Show Source):
You can put this solution on YOUR website! Hi there,
The ratio of natural to synthetic oil
= 5:3
If 440 liters have to be made then,
Add 5 + 3 = 8
So, 5/8 of 440 liters will be = 275 liters of natural oil
and, 3/8 of 440 liters will be = 165 liters of synthetic oil
Hope this helps :-)
