What to Focus On

  • Ratio compares two quantities of the same kind.
  • a:b means a/b.
  • a is antecedent and b is consequent.
  • Compound ratio is found by termwise multiplication.
  • Duplicate ratio of a:b is a²:b².
  • Triplicate ratio of a:b is a³:b³.
  • Four quantities are in proportion when the first-second ratio equals the third-fourth ratio.
  • a and d are extremes.
  • b and c are means.

Common Mistakes to Avoid

A ratio can be formed between any two quantities, even if they are of different kinds.

The order of terms in a ratio does not matter.

A ratio has units because the original quantities have units.

Memory Tips
