Fraction Calculator: Simplify Complex Math

Add, subtract, and simplify fractions instantly.

Whether you are scaling a recipe in the kitchen, measuring wood for a home project, or helping your child with middle-school math, working with fractions can be tricky. Our Fraction Calculator takes the guesswork out of the process, providing step-by-step results for mixed numbers, improper fractions, and proper fractions alike.

How to Work with Fractions

On familyhealthcalc.com, we don’t just give you the answer; we help you understand the logic behind it:

1. Common Denominators

To add or subtract fractions, they must have the same “bottom number.”

Example: To add ¼ and ½, we convert ½ to 2/4. Result: 1/4 + 2/4 = 3/4.

2. Multiplying & Dividing

• Multiplication: Simply multiply the tops (numerators) and the bottoms (denominators).
• Division: Use the “Keep, Change, Flip” method. Keep the first fraction, change the sign to multiplication, and flip the second fraction upside down.

3. Mixed Numbers vs. Improper Fractions

A mixed number (like 1 ¹/₂) can be converted to an improper fraction (like ³/₂) to make calculations easier. Our calculator handles both formats automatically.

Practical Family Uses

• Cooking & Baking: If a recipe serves 4 and you need to serve 6, use the calculator to multiply measurements like $3/4$ cup by $1.5$.
• Construction & DIY: When working with imperial measurements in the US and Canada, adding $5/8″$ and $3/16″$ is a breeze.
• Education: A perfect tool for parents to verify their children’s math homework and explain the “lowest common denominator.”
