To find the total number of problems on the test, we can set up the equation based on the percentage score. If 12 problems correct correspond to an 80% score, we can express this as: ( 0.80 \times \text{total problems} = 12 ). Solving for total problems, we get: ( \text{total problems} = \frac{12}{0.80} = 15 ). Therefore, there are 15 problems on the test.

To calculate the number of correct answers you got on a test, you can use the formula: (score / total possible score) x total number of questions. In this case, you got a score of 78 on a 65-question test. So, (78 / 100) x 65 = 50.7. Therefore, you got approximately 51 questions correct on the test.
