Final answer:
You would need 4 teaspoons of oregano for a single can of tomatoes.
Step-by-step explanation:
To find out how many teaspoons of oregano are needed for a single can of tomatoes, we can set up a proportion using the given information. Since there are 11 cans of tomatoes and 44 teaspoons of oregano, we can write the proportion:
11 cans / 44 teaspoons = 1 can / x teaspoons
To solve for x, we can cross-multiply and divide:
11x = 44
x = 44 / 11
x = 4
Therefore, you would need 4 teaspoons of oregano for a single can of tomatoes.
