To find out how much oil needs to be blended with 7 liters of vinegar, we can use the ratio of oil to vinegar.
The ratio of oil to vinegar in the salad dressing is 8:5.
This means that for every 8 parts of oil, there are 5 parts of vinegar.
To determine how much oil is needed, we need to find the equivalent ratio for 7 liters of vinegar.
The ratio of vinegar is 5 parts out of 13 parts (8 + 5) because 5/(5+8) = 5/13.
Since we know that there are 7 liters of vinegar, we can set up the following proportion:
Vinegar/Oil = 7/x
Cross multiply:
5x = 7 * 13
5x = 91
Divide both sides by 5:
x = 91/5
x ≈ 18.2
Therefore, approximately 18.2 liters of oil must be blended with 7 liters of vinegar for that recipe.
To find out how much oil must be blended with 7 liters of vinegar to maintain the ratio of 8:5, we need to set up a proportion.
Ratio of oil to vinegar = 8:5
We can set up the proportion as follows:
oil/vinegar = 8/5
We know the amount of vinegar is 7 liters, so we can substitute:
oil/7 = 8/5
To solve this proportion, we can cross-multiply:
5 * oil = 8 * 7
5 * oil = 56
To isolate the oil, divide both sides of the equation by 5:
oil = 56/5
Therefore, to maintain the ratio of 8:5, we need to blend approximately 11.2 liters of oil with 7 liters of vinegar for that recipe.
