A recipe for salad dressing calls for 1/4 cup of vinegar. You have 4 cups of vinegar. How many batches of salad dressing could you with the vinegar?

There are several information’s of immense importance already given in the question. Based on those information’s the answer can be easily deduced.

Amount of vinegar required for making 1 recipe of salad dressing = 1/4 cup

Amount of vinegar available = 4 cups

Then

The number of salad dressings that could be made = [1 / (1/4) ] * 4

= 4 * 4

= 16

So 16 salad dressings could be made with the amount of vinegar available. I hope the procedure is clear enough for you to understand.
