In this unit students will learn how to

  • define ratio, proportions and variations (direct and inverse).
  • find 3rd, 4th, mean and continued proportion.
  • apply theorems of invertendo, alternendo, componendo, dividendo and compnendo and dividendo to find proportions
  • define joint variation.
  • solve problems related to joint variation.
  • use k-method to prove conditional equalities involving proportions.
  • solve real life problems based on variations.
