Question

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 7 liters of synthetic oil. If 852 liters of synthetic oil are used, how many liters of petrolyn oil will be made?

Answer 1

Answer:

Therefore 1,460.57 liters will be made of petrolyn oil.

Step-by-step explanation:

Given that,

Petrolyn motor oil contains 5 liters of natural oil for every 7 liters of synthetic oil.

(7+5) liters= 12 liters petrolyn motor oil is made by 7 liters of synthetic oil and 5 liters of natural oil.

7 liters of  synthetic oil used to made of 12 liters Petrolyn motor oil.

1 liters of  synthetic oil used to made of  $\frac{12}7$ liters Petrolyn motor oil.

852 liters of  synthetic oil used to made of $\frac{12\times 852}{7}$ liters Petrolyn motor oil.

                                                                   = 1,460.57 liters

Therefore 1,460.57 liters will be made of petrolyn oil.
