How to work it out

  1. Simplify: 20/72 = 5/18 (divide by 4)
  2. Divide the numerator by the denominator: 20 ÷ 72 = 0.27777778
  3. The digits in brackets repeat forever: 0.2(7)
  4. Check: Work backwards: 0.277778 × 72 = 20, which is 20 once rounding is allowed for.

In a spreadsheet: =20/72. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
