Fractions on Google Calculator
Google's calculator turns fractions into decimals. This one doesn't. Add, subtract, multiply, or divide any two fractions or mixed numbers and get the exact reduced answer, the mixed number, the decimal, and the full step-by-step work — plus a visual fraction bar so you can see it, not just read it.
Type a fraction like 3/4 into Google search and it returns a decimal (0.75), not a fraction. To get an exact fraction answer for adding, subtracting, multiplying, or dividing two fractions, use a calculator built for fractions — like the one below, which also reduces the result and shows it as a mixed number.
Why Google's calculator doesn't give you a clean fraction answer
Type 3/4 into the Google search bar and you'll get 0.75 almost instantly — Google's built-in calculator reads the forward slash as plain division, the same way it would read any other arithmetic symbol. That's fine for a single fraction, but it falls apart the moment you try to combine two of them. Search for 3/4 + 5/8 and Google evaluates the whole expression as decimal division and addition, landing on 1.375. It never finds a common denominator, never reduces anything to lowest terms, and never tells you the answer is actually 11/8, or 1 3/8 as a mixed number.
There is a workaround built into Google search: typing a decimal followed by "to fraction" (for example, "1.375 to fraction") will convert that single value back into a fraction. It's a useful trick, but it only works on one number at a time, requires you to already have the decimal in hand, and still won't show any of the actual math behind the answer. That two-step, decimal-then-convert process is exactly what this calculator skips — enter both fractions once, pick an operation, and get the exact fraction, the mixed number, and the decimal together, instantly.
How to add and subtract fractions
Fractions can only be added or subtracted once they share the same denominator. If the denominators don't already match, find the least common denominator (LCD) — the smallest number both denominators divide into evenly — then rewrite each fraction using that denominator by multiplying its numerator and denominator by whatever factor gets it there. Once both fractions share a denominator, simply add or subtract the numerators and keep the denominator unchanged. Finally, reduce the result to lowest terms and convert it to a mixed number if the numerator ends up larger than the denominator.
This same "find a common denominator" logic shows up well beyond classroom fraction problems. Probabilities are fractions too — the chance of rolling any specific sum on a pair of dice is expressed as a fraction of total outcomes, and combining probabilities across multiple rolls uses the exact same addition rules. If you're working through dice probability or expected-value problems, our dice average calculator handles that side of the math directly.
How to multiply and divide fractions
Multiplication is the simplest fraction operation, and it doesn't need a common denominator at all — multiply the two numerators together to get the new numerator, multiply the two denominators together to get the new denominator, then simplify.
Division uses a method commonly remembered as "keep, change, flip": keep the first fraction exactly as it is, change the division sign to multiplication, and flip the second fraction upside down by swapping its numerator and denominator. From there it becomes a normal multiplication problem — multiply across, then reduce the result to lowest terms.
Mixed numbers, decimals, and where fractions show up in computing
An improper fraction like 11/8 and a mixed number like 1 3/8 represent the exact same value — improper fractions are usually easier to calculate with, while mixed numbers are usually easier to read at a glance, which is why this calculator always shows both. Converting between a fraction and a decimal just means dividing the numerator by the denominator; converting the other direction means recognizing what power of 10 (or what simpler ratio) the decimal represents, then reducing.
Fractions and decimals aren't the only number systems worth converting between. Computers don't store numbers in base 10 at all — they use binary, so a decimal value coming out of a fraction calculation often needs a second conversion step if you're working on anything programming-related. Our decimal to binary converter picks up exactly where this tool leaves off, turning a decimal result into its binary representation.

More calculators for numbers and logic
Fraction math is one specific case of a much bigger idea: combining values using a defined set of operators and rules. Addition, subtraction, multiplication, and division are the operators for numeric fractions, but other branches of math run on entirely different operator sets applied to entirely different kinds of values. If your work involves true/false logic instead of numeric fractions, our boolean algebra calculator applies that same idea of combining values through defined operations, just using AND, OR, and NOT instead of plus, minus, times, and divide.
Fractions on Google calculator — FAQ
Why does Google's calculator give me a decimal instead of a fraction?
Google's search bar treats the forward slash as a plain division operator, so typing something like 3/4 + 5/8 just computes the decimal result of that expression rather than working with the fractions as fractions. It doesn't automatically find a common denominator, combine numerators, or reduce the answer to lowest terms — it just hands you a decimal like 1.375, which is mathematically correct but not what most people are actually looking for when they ask for a fraction answer.
How do I force Google search to show a fraction instead of a decimal?
Google does support a conversion trick: typing a decimal followed by "to fraction" or "as a fraction" (for example, "1.375 to fraction") will return the equivalent fraction. The catch is that this only works on a single decimal value you already have — it won't add or subtract two fractions directly and return a fraction answer, won't show a mixed number automatically, and won't show any of the work. You'd still need to calculate the decimal first, then run a second search to convert it back.
How do you add or subtract fractions with different denominators?
You can't combine numerators until both fractions share the same denominator. Find the least common denominator (the smallest number both denominators divide into evenly), rewrite each fraction with that denominator by multiplying its numerator and denominator by the same factor, then add or subtract the numerators while keeping the shared denominator. Finally, reduce the result to lowest terms and convert it to a mixed number if the numerator is larger than the denominator.
How do you multiply and divide fractions?
Multiplying is the most direct fraction operation: multiply the two numerators together, multiply the two denominators together, then simplify. Dividing uses the "keep, change, flip" method — keep the first fraction as it is, change the division sign to multiplication, and flip the second fraction upside down (swap its numerator and denominator), then multiply as usual and reduce the result.
What's the difference between an improper fraction and a mixed number?
An improper fraction has a numerator larger than its denominator, like 11/8, which represents a value greater than one whole. A mixed number expresses that same value as a whole number plus a proper fraction, like 1 3/8. Both represent the identical quantity — improper fractions are usually easier to do math with, while mixed numbers are usually easier to read, which is why this calculator shows both.
What does it mean to simplify or reduce a fraction?
Simplifying a fraction means dividing both the numerator and denominator by their greatest common factor (GCF) until no whole number larger than 1 can divide them both evenly. For example, 6/8 simplifies to 3/4 because dividing both numbers by their GCF of 2 produces the same value in a smaller, cleaner form. A simplified fraction always represents the exact same value as the original, just written with smaller numbers.
How do negative fractions work in calculations?
A fraction is negative if either the numerator or the denominator (but not both) is negative — the negative sign can be thought of as sitting in front of the whole fraction. If both the numerator and denominator are negative, the negatives cancel out and the fraction is positive, following the same sign rules used for negative numbers generally. This calculator accepts a negative whole number or negative numerator for any fraction you enter.
Can this calculator handle mixed numbers, not just simple fractions?
Yes. Each fraction field includes an optional whole-number part, so you can enter something like 2 3/4 directly instead of converting it to an improper fraction yourself first. The calculator converts mixed numbers internally before doing the math, then converts the final answer back into both an improper fraction and a mixed number so you can see the result either way.
