Frequently Asked Questions

How do I add fractions with different denominators?

Find the least common denominator (LCD), convert each fraction to have that denominator, then add the numerators and keep the denominator. Example: 1/3 + 1/4 → LCD=12 → 4/12 + 3/12 = 7/12. Simplify the result if possible.

How do I convert a decimal to a fraction?

Write the decimal over 1 (e.g., 0.75/1), multiply both top and bottom by 10, 100, or 1000 to eliminate the decimal (75/100), then simplify by dividing by GCD (3/4). This calculator converts instantly in both directions.

How do I multiply fractions?

Multiply numerators together and denominators together: (a/b) × (c/d) = (a×c)/(b×d). Example: 2/3 × 3/4 = 6/12 = 1/2. Always simplify the result. Cross-cancellation before multiplying can make the numbers smaller and easier to work with.

How do I divide fractions?

Flip the second fraction (find its reciprocal), then multiply: (a/b) ÷ (c/d) = (a/b) × (d/c). Example: 3/4 ÷ 2/5 = 3/4 × 5/2 = 15/8 = 1 7/8. Enter any fraction division in this calculator for step-by-step results.

How do I simplify a fraction to its lowest terms?

Divide both the numerator and denominator by their greatest common divisor (GCD). For 12/18, the GCD is 6, so it simplifies to 2/3. The calculator reduces any fraction to lowest terms automatically and shows the equivalent decimal; Learning mode adds a visual bar/circle/grid representation alongside the result.
