To determine the percentage score based on a test score, you need to divide the number of correct answers by the total number of questions on the test and then multiply by 100 to convert it into a percentage format.

In this case, the calculation is as follows:

1. Take the number of correct answers, which is 18.

2. Divide this number by the total number of questions, which is 20.

- This gives you 18 ÷ 20 = 0.9.

3. To convert this decimal into a percentage, multiply by 100.

- So, 0.9 × 100 = 90%.

Thus, scoring 18 out of 20 results in a percentage score of 90%. This demonstrates how to compute a percentage from a fraction by applying division and multiplication, ensuring a clear understanding of the relationship between correct responses and total possible responses.
