2005-: Numeric Proportionality 1

BACK to Ladder Proportionality

Direct Proportion

  1. A and B are directly proportional.
    1. If A is doubled, what happens to B?
    2. If B is doubled, what happens to A?
    3. A has a value of 40. B has a value of 30. The value of A increases to 160. What is the new value of B?
  2. C and D are directly proportional. C has a value of 6 and D has a value of 0.01. If C is decreased to 3, what is the new value of D?

Inverse Proportion

  1. E and F are inversely proportional. When E has a value of 5, F has a value of 11. When E is increased to 15, what is the new value of F?
  2. G and H are inversely proportional. When G has a value of one million, H has a value of 6. When G is decreased to 500,000, what is the new value of H?
  3. I and J are directly proportional. When I has a value of 4000, J has a value of 0.0002. When I is increased to 16000, what is the new value of J?
  4. K and L are inversely proportional. When K has a value of \( 8 \cdot 10^{-10} \), L has a value of 4 million. If the value of L is increased to 8 million, what is the new value of K?
  5. M and N are directly proportional. When M has a value of \( 3 \cdot 10^4 \), N has a value of \( 6 \cdot 10^{-8} \). When M is increased to \( 3 \cdot 10^6 \), what is the new value of N?

Add and Subtract?

Proportionality only gives you information about division and multiplication, it does not give you any information about addition or subtraction.
