Final answer:

Annie worked for 5 hours to prepare 30 kilograms of dough.


Step-by-step explanation:

Let's use a proportion to solve this problem. We can set up the equation:

2 hours / 12 kilograms = x hours / 30 kilograms

Cross multiplying, we get:

2 * 30 = 12 * x

Simplifying, we find that x = 5. So, Annie worked for 5 hours to prepare 30 kilograms of dough.
