How do I simplify a fraction?

Find the greatest common divisor (GCD) of numerator and denominator, then divide both by it. For example: 12/18 - GCD is 6, so 12/18 = 2/3.

How do I convert a mixed number to improper fraction?

Multiply the whole number by the denominator, add the numerator, put over original denominator. Example: 3¼ = (3×4+1)/4 = 13/4.

Division by zero is mathematically undefined. If your denominator is zero, the fraction doesn't exist. A fraction requires a non-zero denominator.

The Mathematical Formula

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

Fraction operations:

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

Subtraction: a/b - c/d = (ad - bc) / bd

Multiplication: a/b × c/d = ac / bd

Division: a/b ÷ c/d = a/b × d/c = ad / bc

Simplification: Divide numerator and denominator by GCD

Mixed numbers: 3½ = (3×2 + 1)/2 = 7/2
