Key Differences
Percent is a mathematical term used to describe a quantity as a fraction of 100, indicating how many parts out of a hundred a certain value represents. Ratios, on the other hand, compare two quantities to show their relative sizes, not necessarily out of a hundred.
While percents are often used to describe changes in quantities, proportions, or to compare differences within a whole, ratios provide a direct comparison between two quantities, illustrating how much of one thing there is compared to another. Percentages are typically represented with the "%" symbol, conveying parts per hundred, whereas ratios are expressed using the ":" symbol or the word "to", highlighting the comparative nature between two numbers.
The application of percent is widespread in financial contexts, statistics, and daily life to convey information in a universally understood format—parts per hundred. Ratios, however, are more versatile in their application, from comparing quantities in recipes, to expressing odds in probabilities, or representing scale in models and maps.
Percents are inherently tied to a base of 100, making them particularly useful for expressing proportions and fractions in an easily digestible format. Ratios do not adhere to this base-100 constraint, offering a more flexible comparison that can articulate any relationship between numbers, regardless of scale or magnitude.

Definition
A part per hundred of anything.
A relationship between two numbers showing how many times the first number contains the second.

Expression
Represented by the "%" symbol.
Expressed as "a:b" or "a to b".
Use
To express fractions, proportions, or changes as parts of 100.
To compare quantities directly, without a fixed base.
Example
50% means 50 out of 100.
The ratio 1:2 means for every 1 of the first item, there are 2 of the second.

Common Curiosities
What is the difference between percent and percentage?
Percent refers to a specific part per hundred, while percentage is the amount or proportion represented as a percent.
Can ratios be converted to percents?
Yes, by finding the equivalent fraction out of 100, ratios can be expressed as percents.
Can a ratio represent parts of a whole like percent?
Yes, ratios can express parts of a whole but in a direct comparison between two quantities, not necessarily out of 100.
Are percents always less than 100?
No, percents can be greater than 100 when representing quantities larger than the whole.
What does a 1:1 ratio mean?
A 1:1 ratio means that there are equal quantities of two items being compared.
How do you find a percent of a number?
Multiply the number by the percent (as a decimal) to find the part of the whole it represents.
Why are percents commonly used in finance?
Percents provide a clear, standardized way to express changes, interest rates, and comparisons in financial terms.
Can ratios be simplified like fractions?
Yes, ratios can be simplified to their lowest terms to express the same relationship in a simpler form.
Why are ratios important in real-life applications?
Ratios are crucial for practical comparisons, such as mixing ingredients, creating scale models, or calculating probabilities.
How is a percent different from a fraction?
A percent is a specific type of fraction with a denominator of 100, while fractions can have any denominator.
Is a percent a type of ratio?
Yes, a percent is essentially a ratio with a standard second term of 100.
What is the significance of a ratio in recipes?
Ratios in recipes ensure the correct balance of ingredients for the desired outcome, regardless of the quantity being made.
How does a ratio differ in use from a fraction?
While both compare quantities, fractions are part of a whole, and ratios compare two distinct quantities.
What role do percents and ratios play in data analysis?
They are used to compare data sets, measure changes over time, and understand relationships within data.
How do percents relate to decimal numbers?
