Formula used

Find the numerator and denominator, with denominator at or below the selected limit, that minimises |decimal − numerator ÷ denominator|. Simplify by dividing numerator and denominator by their greatest common divisor. Percentage = decimal × 100. Optional multiplied value = decimal × quantity.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Best for maths worksheets, recipe scaling, product dimensions, construction notes, tape-measure approximations and quote records where the decimal and fraction should stay connected.

  • The calculator approximates the entered decimal using the best denominator up to the selected maximum denominator.
  • The resulting fraction is simplified by the greatest common divisor and keeps any negative sign on the numerator.
  • A terminating decimal may still be rounded by the user interface before it is typed; keep the source value visible for auditability.
  • A smaller denominator is easier to read but may create a larger approximation error than a larger denominator.
  • For formal exams, engineering tolerances, recipe scaling, machining or accounting records, use the required rounding and tolerance rule.

Master’s Tip

How to use the result well

Master’s Tip: choose the denominator for the job, not just the neatest looking answer. A classroom worksheet may want eighths or sixteenths, while a technical record may need a larger denominator and a visible error check.

Method

Find the numerator and denominator, with denominator at or below the selected limit, that minimises |decimal − numerator ÷ denominator|. Simplify by dividing numerator and denominator by their greatest common divisor. Percentage = decimal × 100. Optional multiplied value = decimal × quantity.

  1. For 0.375 with maximum denominator 1,000, the exact simplified fraction is 3/8 because 3 ÷ 8 = 0.375. As a percentage, 0.375 × 100 = 37.5%.

Assumptions

  • The calculator approximates the entered decimal using the best denominator up to the selected maximum denominator.
  • The resulting fraction is simplified by the greatest common divisor and keeps any negative sign on the numerator.
  • A terminating decimal may still be rounded by the user interface before it is typed; keep the source value visible for auditability.
  • A smaller denominator is easier to read but may create a larger approximation error than a larger denominator.
