Final answer:
Tameka answered 24 out of the 30 questions correctly on the test, which is 80% of the total questions.
Step-by-step explanation:
To find out how many questions Tameka got correct on Mrs. Nelson's 30-question test, we calculate 80% of 30. First, we convert the percentage to a decimal by dividing by 100, which gives us 0.8. Then, we multiply 30 (the total number of questions) by 0.8 (the decimal form of 80%).
30 questions × 0.8 = 24 questions
Tameka correctly answered 24 questions on the test, which is 80% of the total questions.
