What is a Fraction?

A fraction represents a part of a whole. It has a numerator (top number) and a denominator (bottom number). For example, 3/4 means 3 parts out of 4 equal parts.

How to Simplify a Fraction

To simplify a fraction, divide both numerator and denominator by their greatest common divisor (GCD). For example, 6/8 simplifies to 3/4 because the GCD of 6 and 8 is 2.

Converting Fractions and Decimals

• Fraction → Decimal: Divide the numerator by the denominator. 3/4 = 3 ÷ 4 = 0.75
• Decimal → Fraction: Write the decimal with denominator 10, 100 or 1000 and simplify. 0.75 = 75/100 = 3/4
• Mixed Number → Fraction: Multiply the whole number by the denominator, add the numerator and keep the denominator. 1 3/4 = 7/4
