Multiple fraction calculator

Add, subtract, multiply or divide any number of fractions in one go — not just two. Enter as many numerator/denominator rows as you like, pick the operation, and it chains them left to right and reduces the answer to lowest terms, with the decimal and mixed-number forms.

Frequently asked questions

What is Multiple fraction calculator?

Add, subtract, multiply or divide any number of fractions in one go — not just two. Enter as many numerator/denominator rows as you like, pick the operation, and it chains them left to right and reduces the answer to lowest terms, with the decimal and mixed-number forms.

What does a concrete case look like?

1/2 + 1/3 + 1/6 = 1 — the tool shows every step in between, not just the final figure.

When would I actually use this?

Reading a number written another way: a Roman numeral on a monument, a hexadecimal colour, a binary byte, or a fraction that needs reducing.

What is the most common mistake?

Assuming a decimal fraction survives a change of base. A tenth is exact in decimal and infinitely repeating in binary, which is why 0.1 + 0.2 is not 0.3 in most programming languages.

How is Multiple fraction calculator different from Continued fraction calculator?

They sit next to each other but answer different questions: Continued fraction calculator is the one to open when you need it to expand a number into its continued fraction [a₀; a₁, a₂, …] and list the convergents — the best rational approximations at each step. Feed it a decimal, an exact fraction a/b, or a square root √k: rationals terminate, √k is periodic, and irrationals stream on to the term cap. Continued fractions give the closest fractions for a given size of denominator and reveal the hidden structure of numbers like the golden ratio and π. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Decimal to fraction calculator is the closest one after this: Convert a decimal number into a simplified fraction.

What else is worth having open alongside it?

Egyptian fraction calculator and Fraction Calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Base conversion and number-theory results are exact. Roman numerals follow the standard subtractive form used since the Middle Ages, which is not the only one the Romans themselves used.
