Question

Trevor made a batch of salad dressing. He used 3 times as much oil as vinegar. If Trevor used 9 tablespoons of oil, how many tablespoons of vinegar did he use?

Answer 1

3 tablespoons of vinegar

Explanation:

First, this question direction's aren't really clear because the question is saying from my perspective:

Trevor used 2 things: Oil and Vinegar.

Then it says he used 3 times as much oil as vinegar

After it says he used 9 tablespoons of oil.

Lastly, the question asks for how many tablespoons of vinegar did he use?

9 Table Spoons of Oil is the Constant Variable or something that doesn't change in the problem

If he used 3 times as much oil then the equation would be

n x 3 = 9

n is representing the vinegar, 3 is representing the "3 times", 9 is the amount of oil Trevor uses.

You would then do 9/3 (9 divided by 3 since we are doing opposite operations to solve for n) which is equal to 3

In conclusion,

We needed to find the number of tablespoons of vinegar that Trevor used in his salad dressing, we know that 9 tablespoons is representing his oil, we wanted to find a number that is 3 times the tablespoons of vinegar but equalling to 9 since the oil is 3 times the vinegar. So the equation is n x 3 =9

Therefore, n=3 tablespoons of vinegar

Answer 2

Trevor used 3 tablespoons of vinegar in his salad dressing since he used three times as much oil (9 tablespoons) as vinegar.

The question asks us to find out how many tablespoons of vinegar Trevor used if he made a batch of salad dressing using three times as much oil as vinegar, with 9 tablespoons of oil. To solve this problem, we simply divide the amount of oil by three, since there is three times as much oil as vinegar.

Begin with the amount of oil Trevor used: 9 tablespoons.

Since the ratio of oil to vinegar is 3:1, divide the tablespoons of oil by 3 to find the tablespoons of vinegar.

9 tablespoons of oil ÷ 3 equals n=3 tablespoons of vinegar.
