According to a salad recipe, each serving requires 3 teaspoons of vegetable oil and 12 teaspoons of vinegar. If 17 teaspoons of vegetable oil were used, how
many teaspoons of vinegar should be used? How do I solve this? 
17 teaspoons of vegetable oil compares to 3 teaspoons of vegetable oil as

x  teaspoons of vinegar compares to 12 teaspoons of vinegar. 


17 is to 3 as x is to 12

"Is to" means "over" and "as" means equal



Cross multiply





Divide both sides by 3





So the answer is that you would use 68 teaspoons.
