It is B. You will take 3 times 3 which is 9 then you would take 4 times 3 which is 12. so your ratio would be 9:12.
The expression that describes the ratio of teaspoons of sugar to salt you will use is 9: 12
If a cookie mixture requires 3 teaspoons of sugar for every 4 teaspoons of salt, the ratio of sugar to cookies to teaspoon will be expressed as
sugar: teaspoon = 3: 4
If the mixture is tripled, we will simply multiply the ratio by the scale factor which is 3 as shown:
New ratio of sugar to teaspoon = 3(3) : 3(4)
New ratio of sugar to teaspoon = 9: 12
Hence the expression that describes the ratio of teaspoons of sugar to salt you will use is 9: 12
