Question: A clinic administered the covid vaccine to 650 people. 80% of the people were adults. How many of the vaccinated people were children? Is final answer 129?
Answer: Since 80% of the people were adults, this means 100% - 80% = 20 % were children.
20% of the people vaccinated were children. The number of children is 20% of 650.
20% = 0.2, so 0.2 * 650 = <<0.2*650=130>>130 children were vaccinated.
