Final answer:
To find the percentage of multiple choice questions on the math test, divide the number of multiple choice questions (12) by the total number of questions (15) and multiply by 100, resulting in 80% of the test being multiple choice.
Step-by-step explanation:
To calculate what percent of the questions are multiple choice on the math test, we use the following steps:
- First, we need to know the total number of questions on the test, which is 15.
- Then, we determine the number of multiple choice questions, which is 12.
- To find the percentage, we divide the number of multiple choice questions by the total number of questions and then multiply by 100 to change the decimal to a percentage. So, the calculation is (12 / 15) × 100.
- Performing the calculation gives us 0.8 × 100, which equals 80%.
Therefore, 80% of the questions on the math test are multiple choice.
