370 liters
The problem states that you can make 5 liters of the synthetic oil for every 4 liters of natural oil. So you simply divide the amount of natural oil you have by 4 and then multiple the result by 5 to get the amount of synthetic oil produced. The formula is
V = N/4 * 5
Substituting the known value of 296 for N gives
V = 296 / 4 * 5 = 74 * 5 = 370
So you can make 370 liters of Petrolyn oil from 296 liters of natural oil.
