How to work it out

  1. Simplify: 27/66 = 9/22 (divide by 3)
  2. Divide the numerator by the denominator: 27 ÷ 66 = 0.40909091
  3. The digits in brackets repeat forever: 0.4(09)
  4. Check: Work backwards: 0.409091 × 66 = 27, which is 27 once rounding is allowed for.

In a spreadsheet: =27/66. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
