How to work it out

  1. Simplify: 15/90 = 1/6 (divide by 15)
  2. Divide the numerator by the denominator: 15 ÷ 90 = 0.16666667
  3. The digits in brackets repeat forever: 0.1(6)
  4. Check: Work backwards: 0.166667 × 90 = 15, which is 15 once rounding is allowed for.

In a spreadsheet: =15/90. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
