Fraction Rules & Formulas

Our calculator applies standard algebraic rules to ensure precision. Here is the logic used for the calculations:

Addition & Subtraction

Requires a common denominator.

a/b + c/d = (ad + bc) / bd
a/b – c/d = (ad – bc) / bd

Multiplication & Division

Multiply straight across or flip to divide.

(a/b) × (c/d) = (ac) / (bd)
(a/b) ÷ (c/d) = (a/b) × (d/c) = (ad) / (bc)

Frequently Asked Questions (FAQ)

What is a Common Denominator? ▼

A common denominator is a shared multiple of the denominators of two or more fractions. It is required to add or subtract fractions. For example, to add 1/2 and 1/3, the common denominator is 6.

How do I multiply fractions? ▼

Multiplying fractions is straightforward: simply multiply the numerators (top numbers) together and the denominators (bottom numbers) together. Then simplify the result.

What is a Mixed Number? ▼

A mixed number is a combination of a whole number and a fraction (e.g., 2 ½). Our calculator can convert improper fractions (where the top is larger than the bottom) into mixed numbers automatically.

Can this calculator handle negative fractions? ▼

Yes. You can input negative values. The calculator follows standard rules for positive and negative numbers during the calculation.

How do I divide fractions? ▼

To divide fractions, you multiply the first fraction by the reciprocal (flip) of the second fraction. For example, dividing by 1/2 is the same as multiplying by 2/1.

Is the Nexli Fraction Calculator free? ▼

Yes, the Nexli Fraction Calculator is 100% free for students, teachers, and professionals to use as often as needed.
