Frequently Asked Questions
How do you simplify a ratio?
To simplify a ratio, divide both numbers by their Greatest Common Divisor (GCD). For example, 15:25 simplified is 3:5 (both divided by 5).
What is a ratio used for?
Ratios compare quantities. They're used in recipes (ingredient proportions), maps (scale), finance (debt-to-income), and more. They show relative sizes without specific amounts.
How do I find an equivalent ratio?
Multiply or divide both parts of a ratio by the same number. For example, 2:3 is equivalent to 4:6 (multiplied by 2) and 6:9 (multiplied by 3).
