In a mixture of 90 liters, the ratio of vinegar to water is 1:4. How many liters of vinegar are there?

Correct Answer: 18 liters

Step 1: Understand the total mixture is 90 liters.
Step 2: The ratio of vinegar to water is 1:4. This means for every 1 part vinegar, there are 4 parts water.
Step 3: Add the parts of vinegar and water together: 1 (vinegar) + 4 (water) = 5 parts total.
Step 4: To find out how much one part is, divide the total mixture by the total parts: 90 liters ÷ 5 parts = 18 liters per part.
Step 5: Since vinegar is 1 part, the amount of vinegar is 1 part × 18 liters/part = 18 liters.
