Final answer:
In Mathematics, to find 2/3 of the number of questions Juan answered incorrectly (6), we multiply by the fraction 2/3, leading to Lucas incorrectly answering 4 questions. The correct answer choice is A) 4.
Step-by-step explanation:
The subject of this question is Mathematics, specifically dealing with ratios and proportions. Lucas incorrectly answered 2/3 of the number of questions Juan answered incorrectly. Since Juan answered 6 questions incorrectly, we have to find 2/3 of 6 to determine how many Lucas answered incorrectly. To do this calculation:
- Multiply the number of questions Juan got wrong (6) by the fraction 2/3.
2/3 of 6 = (2/3) * 6 = 4
Therefore, Lucas incorrectly answered 4 questions on his math test. The correct choice is A) 4.
