1. Problem Description

The image shows a piece of paper with the text "O que razao?" written on it. The question appears to be in Portuguese and translates to "What ratio?". Since there are no numbers or context provided, it is impossible to solve a specific math problem. The text is simply asking what a ratio is.

2. Solution Steps

A ratio is a comparison between two or more quantities. It indicates how many times one quantity contains or is contained within another. A ratio can be expressed in several ways:

* Using a colon: For example, $a:b$

* As a fraction: For example, $\frac{a}{b}$

* Using the word "to": For example, $a$ to $b$

The ratio between two numbers can be found by dividing the first number by the second.

3. Final Answer

A ratio compares two or more quantities and can be expressed using a colon, as a fraction, or using the word "to".
