Assumptions used

What this answer assumes

Best for maths worksheets, recipe scaling, product dimensions, construction notes, classroom examples and quote records where the fraction and decimal should stay connected.

  • The denominator cannot be zero; if zero is entered, the calculator uses 1 and states the guardrail in the result.
  • The decimal result is based on ordinary real-number division, then rounded only for display.
  • The simplified fraction keeps the sign on the numerator and uses a positive denominator.
  • The repeating-decimal note is a practical warning based on the reduced denominator after factors of 2 and 5 are removed.
  • For formal exams, finance records, engineering drawings or recipes, follow the required rounding rule and keep the original fraction visible.

Master’s Tip

How to use the result well

Master’s Tip: do not round away the original fraction when the value will be reused. Print the fraction, exact division and rounded decimal together so a teacher, cook, estimator or reviewer can see where the decimal came from.

Method

Decimal = numerator ÷ denominator. Percentage = decimal × 100. Simplify the fraction by dividing numerator and denominator by their greatest common divisor. Optional multiplied value = decimal × quantity.

  1. For 3/8, decimal = 3 ÷ 8 = 0.375. As a percentage, 0.375 × 100 = 37.5%. The fraction is already simplified, and because the reduced denominator has only 2 as a prime factor, the decimal terminates.

Assumptions

  • The denominator cannot be zero; if zero is entered, the calculator uses 1 and states the guardrail in the result.
  • The decimal result is based on ordinary real-number division, then rounded only for display.
  • The simplified fraction keeps the sign on the numerator and uses a positive denominator.
  • The repeating-decimal note is a practical warning based on the reduced denominator after factors of 2 and 5 are removed.
