Frequently Asked Questions
How do you simplify a ratio?
Divide both numbers in the ratio by their greatest common factor (GCF). The result is the same ratio in its smallest whole-number form.
What does a ratio of 2:3 mean?
For every 2 units of the first quantity, there are 3 units of the second. It's a relative comparison, not an absolute amount.
Is a ratio the same as a fraction?
They're closely related — 2:3 can be written as the fraction 2/3 — but a ratio compares two separate quantities, while a fraction represents a part of a single whole.
