Answer:
You didn't put any numbers, but I'm going to assume it's 5 liters of natural oil for every 8 liters of synthetic oil and you're asking in order to make 936 liters of petrolyn oil, how many would need to be synthetic. In that case the answer would be 576
Step-by-step explanation:
( natural oil ) / ( synthetic oil ) = 5/8
Let x = liters of synthetic oil needed
936 - x = liters of natural oil needed
5/8=936-x/x
Multiply both sides by 8x
5x=8(936 - x)
5x=7488 - 8x
13x=7488
x=576
