Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 3 liters of natural oil for every
2 liters of synthetic oil. If 198 liters of synthetic oil are used, how many liters of Petrolyn oil will be made?

Best ResponseYou've already chosen the best response.2this will be the basic template \[\Large \frac{\text{amount of natural oil}}{\text{amount of synthetic oil}} = \frac{\text{amount of natural oil}}{\text{amount of synthetic oil}}\]

Best ResponseYou've already chosen the best response.0so then it would be 2x=594?

Best ResponseYou've already chosen the best response.2we know that " It contains 3 liters of natural oil for every 2 liters of synthetic oil" focus on one side, say the right side replace "natural oil" with 3 replace "synthetic oil" with 2 \[\Large \frac{\text{amount of natural oil}}{\text{amount of synthetic oil}} = \frac{\text{amount of natural oil}}{\text{amount of synthetic oil}}\] \[\Large \frac{3}{2} = \frac{\text{amount of natural oil}}{\text{amount of synthetic oil}}\]

Best ResponseYou've already chosen the best response.2yeah you have the right idea, doing 2 more replacements gives \[\Large \frac{3}{2} = \frac{\text{amount of natural oil}}{\text{amount of synthetic oil}}\] \[\Large \frac{3}{2} = \frac{x}{198}\]

Best ResponseYou've already chosen the best response.2and yes, when you cross multiply you will get 2x = 594

Best ResponseYou've already chosen the best response.2297 isn't the amount of Petrolyn oil though 297 is the amount of natural oil

Best ResponseYou've already chosen the best response.2hmm let me think

Best ResponseYou've already chosen the best response.2oh I'm overthinking, yeah we add amount of petrolyn oil = (amount of natural oil) + (amount of synthetic oil)
