Frequently Asked Questions

What is the difference between a ratio and a fraction?

A ratio compares any two quantities (even different units), while a fraction specifically represents parts of a whole. However, ratios can be expressed as fractions.

How do I simplify a ratio?

Divide both numbers by their greatest common divisor (GCD). For example, 12:16 simplifies to 3:4 by dividing both by 4.

Can ratios have more than two parts?

Yes! Ratios can compare any number of quantities. For example, a 1:2:3 cement mixture ratio compares three ingredients.

What is a unit ratio?

A unit ratio has 1 as one of its terms, like 1:5 or 3:1. It shows the amount of one quantity per single unit of another.
