Simplify ratios, compare two quantities and scale recipes or mixes while keeping proportions intact.
Simplified ratio = A : B divided by GCD(A, B)
16:24 shares a greatest common divisor of 8, so it simplifies to 2:3.
A ratio says how many times one quantity contains another. Simplifying keeps the relationship identical while making the numbers easier to reason about — 16 parts to 24 parts behaves exactly like 2 parts to 3 parts.
Ratios appear in cooking (rice to water), mixing fuels, screen aspect ratios, model scales and financial leverage calculations.
Both quantities are equal.
They encode the same relationship, but 2:3 compares two quantities while 2/3 expresses a portion of one whole.
