Two quantities are inversely proportional. What happens to the second one when the first one is increased?
AIt gets larger
BIt stays the same
CIt gets smaller
DIt doubles in size
Answer & Solution
Correct answer: C. It gets smaller
1. Proportion describes how one quantity answers a change in another.
2. Directly proportional quantities move the same way, a more and more relationship.
3. Inversely proportional quantities move opposite ways, so raising one lowers the other.
4. A graph of two inversely proportional quantities is a curve that never cuts either axis.
