In mathematics, percentages are a way of expressing numbers as fractions of 100. They are often used to compare quantities of different sizes. In the given exercise, we are asked to determine what percent of 33 is 11. Here, 'percent' means per hundred.
To convert a number into a percentage, you multiply by 100 and add the percent symbol (%). For example, if you have a fraction \(\frac{1}{2}\), you can find the percentage by calculating \(\frac{1}{2} \times 100 = 50\)%.
Understanding percentages is essential because they appear in various real-life situations like discounts, interest rates, and statistics. A clear grasp of this concept makes it easier to solve problems involving comparisons and proportional relationships.

A proportional relationship is a situation where two quantities increase or decrease at the same rate. In the exercise, we are dealing with the proportional relationship between 33 and 11 and what percentage 11 is of 33.
The equation \(\frac{x}{100} = \frac{11}{33}\) represents this relationship, where x is the unknown percentage. This equation shows that the ratio of x to 100 is the same as the ratio of 11 to 33.
Proportions are helpful because they allow us to scale quantities up or down and compare different situations. In real-life, proportional relationships are commonly used in recipes, maps, and converting units.

Mathematical translation is the process of converting a word problem into a mathematical equation. This step is crucial because it allows you to use algebraic methods to find a solution.
In the given exercise, the statement 'What percent of 33 is 11?' is translated into the mathematical proportion \(\frac{x}{100} = \frac{11}{33}\). Here, x represents the unknown percent.
Translating word problems into mathematical equations often involves identifying keywords and understanding the relationships between the given quantities. This skill is essential for solving complex problems and is widely applicable in various branches of mathematics as well as in real-world scenarios.
