Equivalent fractions are different fractions that represent the same value. Multiplying or dividing both the numerator and denominator by the same non-zero number produces an equivalent fraction. Simplifying a fraction to its lowest terms means dividing by the GCD.

Formel

To find missing numerator: use proportion — a/b = x/d → x = a×d/b

To: x/d → x = a×d/b — x/d → x = a×d/b
b: x/d → x = a×d/b — x/d → x = a×d/b
x: a×d/b — a×d/b

Trin-for-trin guide

1To create an equivalent fraction: multiply top and bottom by the same number
2To simplify: divide top and bottom by their GCD (Greatest Common Divisor)
3To find missing numerator: use proportion — a/b = x/d → x = a×d/b
