Select an operation (+, −, ×, ÷), enter the numerator and denominator of each fraction, and the result appears instantly. The tool automatically simplifies the result and shows it as a decimal and — when applicable — as a mixed number.
Find the Least Common Denominator (LCD), convert both fractions to equivalent fractions with that denominator, then add the numerators. Example: 1/2 + 1/3 — LCD is 6, so 3/6 + 2/6 = 5/6.
Divide both numerator and denominator by their Greatest Common Divisor (GCD). Example: 12/18 — GCD is 6, so 12÷6 = 2 and 18÷6 = 3, giving 2/3.
Divide the numerator by the denominator. The quotient becomes the whole number and the remainder becomes the new numerator. Example: 7/3 — 7 ÷ 3 = 2 remainder 1 = 2 and 1/3.
Yes. Enter a negative numerator (e.g. −3) for a negative fraction. The calculator handles all sign combinations and simplifies correctly.
