Answer:
165 liters.
Step-by-step explanation:
Petrolyn motor oil is a combination or natural oil and synthetic oil.
It contains 3 liters of natural oil for every 2 liters of synthetic oil.
Question asked:
In order to make 275 liters of Petrolyn oil, how many liters of natural oil are needed?
Solution:
It is given that Petrolyn motor oil contains 3 liters of natural oil for every 2 liters of synthetic oil that means ratio of natural oil and synthetic oil is 3 : 2.
Now, in order to make 275 liters of Petrolyn oil, we will have to combine both natural and synthetic oil.
Let ratio be
Then quantity of natural oil in liters =
And quantity of synthetic oil in liters =
To make 275 liters of Petrolyn oil,
Quantity of natural oil in liters + quantity of synthetic oil in liters = 275
Dividing both sides by 5
= liters
Therefore, 165 liters of natural oil are needed to make 275 liters of Petrolyn oil.
