How to work it out

  1. Simplify: 15/66 = 5/22 (divide by 3)
  2. Divide the numerator by the denominator: 15 ÷ 66 = 0.22727273
  3. The digits in brackets repeat forever: 0.2(27)
  4. Check: Work backwards: 0.227273 × 66 = 15, which is 15 once rounding is allowed for.

In a spreadsheet: =15/66. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
