How to work it out

  1. Simplify: 10/42 = 5/21 (divide by 2)
  2. Divide the numerator by the denominator: 10 ÷ 42 = 0.23809524
  3. The digits in brackets repeat forever: 0.(238095)
  4. Check: Work backwards: 0.238095 × 42 = 10, which is 10 once rounding is allowed for.

In a spreadsheet: =10/42. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
