How is the ratio simplified?

Both parts are divided by their greatest common divisor (GCD).

Do a and b have to be integers?

For exact GCD, integers are used. Decimals are converted to a proportional integer ratio first when possible.

The ratio must have at least one non-zero term.

Simplify a ratio a:b to its lowest terms using the GCD (e.g. 8:12 → 2:3).

a (first term)

b (second term)

How is the ratio simplified?: Both parts are divided by their greatest common divisor (GCD).
Do a and b have to be integers?: For exact GCD, integers are used. Decimals are converted to a proportional integer ratio first when possible.
What if the ratio is 0:0?: The ratio must have at least one non-zero term.
