Divide fractions step-by-step using the keep-change-flip method. Supports mixed numbers, whole number divisors, reciprocal display, visual fraction bars, presets, and a detailed steps table.
The **Dividing Fractions Calculator** makes fraction division simple by walking you through the classic "keep-change-flip" method step by step. Enter any two fractions — proper, improper, or mixed numbers — and instantly see the quotient in both fraction and decimal form, along with a fully simplified result.
Dividing fractions is one of the trickier arithmetic operations because it requires converting the problem into multiplication by the reciprocal of the divisor. Many students struggle to remember whether to flip the first or second fraction, and this calculator removes that confusion by showing each transformation clearly. The keep-change-flip rule means: keep the first fraction, change the division sign to multiplication, and flip (take the reciprocal of) the second fraction.
This tool handles mixed numbers by first converting them to improper fractions, then applying the division algorithm. It also supports whole number divisors, treating them as fractions over one. The output includes the reciprocal of the divisor, the multiplication form, cross-simplification opportunities, the unsimplified product, and the final simplified answer.
Visual fraction bars show both the original fractions and the result, making it easier to understand the relative sizes. A detailed steps table breaks the entire process into numbered rows so students can follow along or replicate the work on paper. Use the preset buttons to explore common division problems, or type in your own values for homework help and real-world calculations.
Fraction division often goes wrong at the same place: people forget to flip the second fraction, or they flip the wrong one. This calculator keeps that transformation explicit by showing the reciprocal, the multiplication form, and the simplified product in sequence.
It is also useful when mixed numbers or whole numbers are involved. Instead of handling those conversions separately, you can see the improper fractions, the keep-change-flip step, and the final quotient in one place. That makes the page useful for homework checks, tutoring, recipe scaling, measurement problems, and any situation where you need to explain the method as well as the answer.
a/b ÷ c/d = a/b × d/c = (a × d) / (b × c)
Result: 3/4 ÷ 2/5 = 15/8, which is 1 7/8.
Keep 3/4, change division to multiplication, and flip 2/5 to 5/2. Then multiply: (3 × 5) / (4 × 2) = 15/8.
Dividing by a fraction asks how many copies of that fractional amount fit into the first value. The reciprocal converts that question into multiplication, which is why keep-change-flip works. For example, dividing by 2/5 is the same as multiplying by 5/2.
If either input is a mixed number, convert it to an improper fraction before applying the reciprocal rule. That keeps the arithmetic consistent and makes the simplification steps much easier to audit.
A quotient larger than 1 is common when you divide by a small fraction such as 1/4 or 2/5. A quotient smaller than 1 is common when you divide by a fraction greater than 1. The decimal view and fraction bars help you verify that the answer has the right scale.
Keep the first fraction unchanged, change the division sign to multiplication, and flip the second fraction (use its reciprocal). Then multiply normally.
First convert each mixed number to an improper fraction, then apply the keep-change-flip method and simplify. Doing that first keeps the reciprocal step clear and avoids mixing whole-number parts into the multiplication.
Dividing by a fraction is the same as multiplying by its reciprocal. Flipping the second fraction converts the division into an equivalent multiplication.
Write the whole number as a fraction over 1 (e.g. 3 = 3/1), then flip it to 1/3 and multiply. The same rule works because every whole number can be treated as a fraction with denominator 1.
Yes. The calculator shows the result as both an improper fraction and a mixed number, plus the decimal equivalent.
Find the GCD of the numerator and denominator, then divide both by it. The calculator does this automatically.
The reciprocal of a/b is b/a — you swap the numerator and denominator. The product of a number and its reciprocal is always 1.
