Fraction Calculator - Thai Numerals

How do I add fractions with different denominators?

Enter both fractions in the calculator (e.g., 1/3 + 1/4). The calculator automatically finds the least common denominator (LCD), converts both fractions, and adds them. For 1/3 + 1/4, the LCD is 12, so it becomes 4/12 + 3/12 = 7/12.

How do I convert a decimal to a fraction?

Enter a decimal number like 0.75 or 0.333... in the Decimal to Fraction mode. The calculator converts it to the simplest equivalent fraction — 0.75 becomes 3/4, and 0.333... becomes 1/3. For terminating decimals, the conversion is exact. For repeating decimals, the calculator recognises the repeating pattern and finds the matching rational number.

How do I convert a fraction to a decimal?

Enter a fraction like 3/8 and the calculator divides the numerator by the denominator to get the decimal equivalent: 3/8 = 0.375. The result shows both the exact decimal (for terminating fractions) and a rounded approximation for repeating decimals. For example, 1/3 displays as 0.333... with a note that it repeats.

Can the calculator simplify or reduce fractions automatically?

Yes! The calculator automatically simplifies all results to their lowest terms. For example, 6/8 is automatically reduced to 3/4 by dividing both numerator and denominator by their greatest common divisor (GCD). You can also use the "Simplify Fraction" mode to reduce any fraction directly — enter 12/16 and get 3/4.

How do I use the mixed fraction calculator?

Use the "Mixed Numbers" mode to perform operations with mixed numbers (e.g., 2 1/3 + 1 1/2). Enter the whole number and fraction parts separately. The calculator converts mixed numbers to improper fractions, performs the operation, and provides results in mixed number format. For example, 2 1/3 + 1 1/2 = 3 5/6.

Is this an online fraction calculator?

Yes. This is a free online fraction calculator that runs entirely in your browser with no download or sign-up required. It supports addition, subtraction, multiplication, division, simplification, mixed numbers, and decimal-to-fraction conversion. All calculations happen locally on your device.

How does fraction multiplication work?

To multiply fractions, multiply the numerators together and the denominators together. For example, 2/3 × 3/4 = (2×3)/(3×4) = 6/12, which simplifies to 1/2. The calculator performs this automatically.

How do I divide fractions?

To divide fractions, multiply the first fraction by the reciprocal of the second. For example, 1/2 ÷ 1/4 = 1/2 × 4/1 = 4/2 = 2. Simply enter both fractions and select the division operation, and the calculator handles the rest.

Do people in Thailand actually use Thai numerals day to day?

Yes, though Western numerals are also common. Thai numerals appear on official documents, currency, price tags at markets, and in many printed materials. Many Thais use both systems interchangeably depending on context.

Input: 1/3 + 1/4

Result: LCD = 12. 4/12 + 3/12 = 7/12. Already in lowest terms.

Input: 2 1/3 × 1 1/2

Result: Convert: 7/3 × 3/2 = 21/6 = 7/2 = 3 1/2
