How to work it out

  1. Simplify: 12/45 = 4/15 (divide by 3)
  2. Divide the numerator by the denominator: 12 ÷ 45 = 0.26666667
  3. The digits in brackets repeat forever: 0.2(6)
  4. Check: Work backwards: 0.266667 × 45 = 12, which is 12 once rounding is allowed for.

In a spreadsheet: =12/45. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
