Ratio Simplification & Equivalence Mathematics

Simplifies mathematical ratios (A:B) into lowest integer terms using the Greatest Common Divisor (GCD/HCF), computing decimal ratio values and percentage shares.

Simplified Ratio = (A / GCD(A, B)) : (B / GCD(A, B)) | Fraction = A / (A + B)

Calculation Steps

1Find the Greatest Common Divisor (GCD) of the two ratio terms using Euclidean algorithm.
2Divide both terms by the GCD to find the simplified ratio in lowest terms.
3Calculate decimal quotient: A / B.
4Calculate part-to-whole percentages: [A / (A+B)] * 100 and [B / (A+B)] * 100.
