Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains liters of natural oil for every liters of synthetic oil. In order to make liters of Petrolyn oil, how many liters of synthetic oil are needed?
If Petrolyn motor oil is a combination of natural oil and synthetic oil, and the ratio of natural oil to synthetic oil is 1:4, then for every 1 liter of natural oil, there are 4 liters of synthetic oil.
To make 1 liter of Petrolyn oil, we need 4 liters of synthetic oil.
Therefore, to make 100 liters of Petrolyn oil, we need 4 liters of synthetic oil for every 1 liter, which is a total of 4 * 100 = 400 liters of synthetic oil.
Answer: 400 liters of synthetic oil are needed.
To find out how many liters of synthetic oil are needed, we need to determine the ratio of natural oil to synthetic oil in Petrolyn motor oil.
Let's assume that the ratio of natural oil to synthetic oil is x:1, where x is the number of liters of natural oil for every 1 liter of synthetic oil.
If we have x liters of natural oil for every 1 liter of synthetic oil, then the total amount of oil can be represented as (x + 1) liters.
Now, we know that the total amount of Petrolyn oil needed is liters. Therefore, we can set up the following equation:
x + 1 =
To solve for x, we can subtract 1 from both sides:
x = - 1
Now that we have the value of x, we can determine the number of liters of synthetic oil needed by multiplying x by the total amount of Petrolyn oil needed:
Synthetic oil needed = x * = * =
Therefore, liters of synthetic oil are needed to make liters of Petrolyn oil.
To find out how many liters of synthetic oil are needed to make liters of Petrolyn oil, we need to determine the ratio of natural oil to synthetic oil in the mixture.
The given information states that Petrolyn oil is a combination of natural oil and synthetic oil, with liters of natural oil for every liters of synthetic oil. This tells us that the ratio of natural oil to synthetic oil is liters to .
To calculate the amount of synthetic oil needed, we can set up a proportion:
natural oil : synthetic oil = liters : x liters
Using the ratio from the given information, we can substitute the values into the proportion:
liters : = liters : x liters
Cross-multiplying gives us:
liters × x liters = liters ×
Simplifying further, we have:
liters × x liters = liters ×
Dividing both sides of the equation by liters gives us:
x liters = ( liters × ) /
Therefore, the equation becomes:
x liters = liters ×
Finally, we can calculate the value of x to determine the number of liters of synthetic oil needed.
