What to Focus On

  • Ratio = First quantity ÷ Second quantity
  • Written as a:b, equals a/b
  • First term = antecedent, Second term = consequent

  • Multiplying/dividing both terms by same number keeps ratio unchanged
  • Cross multiplication: a/b vs c/d, compare a×d with b×c
  • Chain ratios: connect multiple quantities through common terms

  • Proportion: a:b::c:d means a/b = c/d
  • Product of extremes = Product of means (a×d = b×c)
  • Mean proportional: if a:b::b:c, then b² = ac

Common Mistakes to Avoid

When comparing two ratios, the one with bigger numerator and denominator is always larger

In inverse proportion, if one quantity doubles, the other becomes half of its original value

In chain ratios like A:B = 2:3 and B:C = 4:5, you can directly write A:B:C = 2:3:4:5
