Learning how to express ratios is essential when discussing proportions or comparing quantities. Whether you’re engaged in mathematics, business, or everyday conversations, being able to convey ratios accurately is important. In this comprehensive guide, we will explore both formal and informal ways to say a ratio, offering tips and examples along the way.

Formal Expressions for Ratios
Formal settings such as academic or professional environments may require a more precise expression of ratios. Here are some formal ways to convey ratios:
1. Using the Word “to”
One common and formal way to express a ratio is by using the word “to” between the two terms being compared. For example:
Example 1: The ratio of boys to girls in the class is 3 to 2.
This expression indicates that for every three boys, there are two girls in the class.
2. Utilizing a Colon
Another formal approach is to use a colon to separate the two quantities in a ratio. For instance:
Example 2: The ratio of red balls to blue balls is 5:2.
This representation indicates that for every five red balls, there are two blue balls.
3. Employing Fraction Form
Ratios can also be presented using fractional form, which may be more suitable in certain mathematical or technical contexts. Consider the following example:
Example 3: The ratio of the circumference to the diameter of a circle is 22/7 or approximately 3.14.
In this case, the ratio is expressed as a fraction, demonstrating that the circumference is 22 times greater than the diameter, or roughly 3.14 times larger in practical terms.
Informal Ways to State a Ratio
In informal situations, such as casual conversations or storytelling, a more simplified expression of ratios may be preferred. Here are some informal ways to talk about ratios:
1. Using “For Every” or “Per”
The phrases “for every” or “per” are commonly used in informal conversations to describe ratios. Let’s look at an example:
Example 4: For every 100 students, there are 3 teachers.
This informal expression means that in a given context, there are three teachers for every one hundred students.
2. Simplified Verbal Descriptions
When informally explaining a ratio, it is acceptable to provide a simplified verbal description rather than a precise numerical representation. Here’s an example:
Example 5: The ratio of coffee to cream in my morning cup is a splash of cream.
In this informal case, the ratio is described as a mere “splash of cream,” giving the listener a general idea of the proportion without exact measurements.
Additional Tips for Expressing Ratios
When stating ratios, regardless of formality, here are some additional tips to help you convey your message accurately:
- Be Consistent: Always keep the order of terms the same. For example, if you say “boys to girls,” maintain the same order throughout the expression.
- Use Clear Terminology: Ensure that the terms being compared are well-defined to avoid confusion. For instance, instead of saying “people to objects,” specify “students to books” for clearer understanding.
- Consider the Context: Adapt your language to the context and audience. Formal settings may require more precise numerical ratios, while informal situations can involve approximations or simpler descriptions.
Remember, ratios are expressions of proportions, and how you say them can greatly impact comprehension and accuracy. Use these guidelines and adapt your approach based on the setting to effectively communicate ratios in a variety of situations.
