Solve fraction work quickly and neatly today. Choose operations, conversions, comparisons, or reduction modes easily. See exact results with helpful steps and cleaner forms.
The calculator treats every value as a numerator over a denominator. It reduces answers with the greatest common divisor.
Add: a/b + c/d = (ad + bc) / bd
Subtract: a/b - c/d = (ad - bc) / bd
Multiply: a/b × c/d = ac / bd
Divide: a/b ÷ c/d = ad / bc
Reduce: n/d = (n ÷ gcd) / (d ÷ gcd)
3/4, 2 1/5, or 0.625.+, -, *, /, and parentheses.| Task | Input | Result | Useful Form |
|---|---|---|---|
| Add | 3/4 + 5/8 | 11/8 | 1 3/8 |
| Subtract | 7/9 - 1/3 | 4/9 | 0.4444 |
| Multiply | 2/5 × 15/8 | 3/4 | 75% |
| Divide | 9/10 ÷ 3/5 | 3/2 | 1 1/2 |
| Simplify | 18/24 | 3/4 | 0.75 |
Fractions look simple, yet they can hide errors. A small denominator mistake can change the answer. This calculator helps you avoid that risk. It reduces every result with a greatest common divisor. It also shows mixed numbers, decimals, and percents. That makes the answer easier to read. Students can check homework. Cooks can scale recipes. Builders can compare sizes. Anyone can use the same clear process.
The calculator handles addition, subtraction, multiplication, and division. It accepts proper fractions, improper fractions, whole numbers, decimals, and mixed numbers. You can enter values like 3/4 or 2 1/5. You can simplify one fraction only. You can compare two values. You can also evaluate a longer expression. Parentheses help control order. The result stays exact before any decimal display appears.
Exact fraction math stores values as a numerator and denominator. The numerator counts selected parts. The denominator tells the size of each part. For addition, both denominators must match. The calculator finds a shared denominator first. Then it adds the adjusted numerators. For multiplication, it multiplies across. For division, it flips the second fraction. Then it multiplies. After each step, it reduces the answer.
A reduced fraction is the cleanest exact form. A mixed number can feel more natural. A decimal helps with measurement. A percent helps with rates. This page gives all these forms together. That saves time. It also helps you learn the link between forms. For example, 1/4 equals 0.25. The same value is 25 percent. These forms look different, but they mean the same amount.
Use a slash between numerator and denominator. Put a space between a whole number and a fraction. Use 1 3/8 for one and three eighths. Do not place zero in the denominator. For expressions, write clear symbols. Use parentheses when the order matters. Check negative signs before submitting. The calculator reads decimals as exact fraction values. That helps avoid rounded answers too early.
Good fraction work should be easy to trace. Read each step from top to bottom. Check the common denominator. Check the sign of every numerator. Check that the final denominator is positive. If a mixed answer looks large, review the improper form. If a decimal looks rounded, trust the exact fraction first. Exact values keep the original math safe. This habit builds confidence and makes future fraction problems faster. It also reduces repeat mistakes.
Fractions appear in school math, shop work, kitchen work, and finance. A carpenter may add 7/16 and 5/8. A baker may multiply 3/4 cup by two. A student may compare 11/12 and 9/10. A shopper may convert a discount into a percent. This calculator supports each case with steps. Accurate fraction answers make every math task feel easier.
Yes. Choose the operation mode. Enter both fractions. Select add. The result appears as a reduced fraction, mixed number, decimal, and percent.
Yes. Use a space between the whole number and fraction. For example, enter 2 1/3. Negative mixed values like -2 1/3 also work.
Yes. Choose simplify and convert mode. Enter one value. The calculator reduces it with the greatest common divisor and shows several matching forms.
Yes. Decimals are converted into exact fractions first. For example, 0.75 becomes 3/4. This keeps the final answer cleaner.
Yes. Choose compare mode. Enter both values. The calculator uses cross multiplication and shows which fraction is larger.
Yes. Parentheses are supported. Use them to control the order of operations in longer fraction expressions.
Use plus, minus, asterisk, slash, parentheses, and the caret. The caret handles whole number powers from -20 to 20.
Yes. Every successful result includes a percent value. It also includes the exact fraction, mixed number, and decimal value.
The calculator stops the calculation and shows an error. A fraction cannot have zero as the denominator.
No. Division by zero is not allowed. The calculator checks this and protects the result from invalid math.
The fraction answer is exact. Decimal and percent forms are displayed for convenience, so they may use limited decimal places.
