The method

Spot the type — “name the topic first, then use its method”

  1. Read the question and name the topic: HCF/LCM, fraction, ratio, percent …
  2. Use that lesson’s method and write each step.
  3. Check: is the answer sensible in size and units?

Use it for: Revising Part 1 before a scholarship, Olympiad or school test.

Worked example: Find the LCM of 4, 6 and 10. → 60

  1. 4 = 2², 6 = 2 × 3, 10 = 2 × 5.
  2. LCM = 2² × 3 × 5 = 60.

Check: 60 ÷ 4 = 15, 60 ÷ 6 = 10, 60 ÷ 10 = 6 ✓
