How to work it out

  1. Simplify: 15/27 = 5/9 (divide by 3)
  2. Divide the numerator by the denominator: 15 ÷ 27 = 0.55555556
  3. The digits in brackets repeat forever: 0.(5)
  4. Check: Work backwards: 0.555556 × 27 = 15, which is 15 once rounding is allowed for.

In a spreadsheet: =15/27. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
