How to work it out

  1. Simplify: 20/78 = 10/39 (divide by 2)
  2. Divide the numerator by the denominator: 20 ÷ 78 = 0.25641026
  3. The digits in brackets repeat forever: 0.(256410)
  4. Check: Work backwards: 0.25641 × 78 = 20, which is 20 once rounding is allowed for.

In a spreadsheet: =20/78. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
