Question

Public health officials believe that 90.5% of children have been vaccinated against measles. A random survey of medical records at many schools across the country found that, among more than 1 million children surveyed, only 890,000 were vaccinated. What percentage of children were not vaccinated?

(A) 10.5%
(B) 9.5%
(C) 10%
(D) 8.95%

Answer 1

To find the percentage of children not vaccinated, subtract the percentage of children vaccinated from 100%.

Step-by-step explanation:

To find the percentage of children not vaccinated, we need to subtract the percentage of children vaccinated from 100%. According to the public health officials, 90.5% of children have been vaccinated against measles. This means that 100% - 90.5% = 9.5% of children were not vaccinated. Therefore, the percentage of children not vaccinated is 9.5%.
