Summarised in our own words. Use the official paper for the exact wording and any diagrams.

Solution · 4 marks

  1. 1Largest f: highest common factor of 14 and 28, f = 14
  2. 2Smallest m: lowest common multiple of 10 and 25, m = 50
  3. 3Smallest p: p = 2
  4. 4f/(mp) = 14/(50 × 2) = 14/100
  5. 5= 0.14
