Can I add a decimal and a fraction?

Yes. Enter values such as 0.5 and 3/4, choose the operation, and the calculator converts both values to fractions before calculating.

Does the calculator support mixed numbers?

Yes. Enter mixed numbers with a space, for example 1 1/2. The result can also be shown as a mixed number.

Why is the answer shown as a fraction and a decimal?

The exact fraction preserves the precise value, while the decimal is useful for checking size and comparing with calculator output.

Can I enter repeating decimals?

No. This page handles terminating decimals such as 0.125. Use the repeating decimal to fraction calculator for values such as 0.(3).

Calculate with fractions, decimals, and mixed numbers

English search results group this task under fraction calculator with decimals and fractions and decimals calculator. The expected tool handles two values, one operation, exact fraction output, mixed-number form, and a decimal check.

Enter a decimal such as 0.5, a fraction such as 3/4, or a mixed number such as 1 1/2.
Choose addition, subtraction, multiplication, or division.
Review the exact fraction, mixed-number form, decimal value, and step-by-step work.

\frac{a}{b} + \frac{c}{d} = \frac{a d + b c}{b d}

For addition and subtraction, convert to a common denominator before combining numerators.

\frac{a}{b} \times \frac{c}{d} = \frac{a c}{b d}, \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

For multiplication and division, work directly with numerators and denominators.

Examples and limits

Input	Operation	Exact result	Decimal
0.5 and 3/4	add	5/4	1.25
1 1/2 and 0.25	subtract	5/4	1.25
2/3 and 1.5	multiply	1	1
0.625 and 5/8	divide	1	1

This calculator is for two values and one operation. Use a dedicated expression solver for long algebraic expressions or the repeating decimal converter for recurring decimals.
