Quizplus · Accepted Answer

The percentage of those that have the disease and tested positive is calculated by dividing the number of people with the disease who tested positive (108) by the total number of people with the disease (120), then multiplying by 100 to get the percentage: $\frac{108}{120} \times 100 = 90%$.
