Final answer:
To find the total number of questions on the assessment, we can set up a proportion using the information given. By cross-multiplying and solving for the total questions, we find that the total number of questions on the assessment was 25.
Step-by-step explanation:
To find the total number of questions on the assessment, we need to set up a proportion using the information given. We know that Juan answered 21 questions correctly out of the total number of questions on the assessment. The score of 84% represents the ratio of correct questions to the total number of questions. We can set up the proportion as:
21/total questions = 84/100
To solve for the total number of questions, we can cross-multiply: 21 x 100 = 84 x total questions. Then, divide both sides by 84 to isolate the total questions: total questions = (21 x 100) / 84. Simplifying this, we get:
total questions = 25
Therefore, the total number of questions on the assessment was 25.
