How to work it out

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

In a spreadsheet: =9/22. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
