Mastering Numbers – How to Write ’45’ in Words and Why It Matters




Writing numbers in words may seem like a small detail, but it can have a significant impact on the readability and clarity of your writing. In this blog post, we will explore the basics of writing numbers in words and focus on the number ’45.’ Mastering the correct usage of ’45’ in words carries numerous advantages and can greatly improve your overall writing skills.

Writing Numbers in Words: The Basics

Before diving into the specific number ’45,’ let’s review some common rules for writing numbers in words. Understanding these guidelines will help you write any number in words accurately and consistently.

Numbers from One to Nine

When writing numbers from one to nine, always use words. For example, instead of ‘1,’ write ‘one.’ This rule applies regardless of the context in which the number appears.

Numbers from Ten to Ninety-Nine

From ten to ninety-nine, use a combination of words and numerals. For instance, use ‘eleven’ instead of ’11’ and ‘eighty-four’ instead of ’84.’ However, there are some exceptions and special cases to keep in mind.

Numbers in the Hundreds and Thousands

When writing numbers in the hundreds and thousands, use a mix of words and numerals. For example, write ‘three hundred’ instead of ‘300’ and ‘four thousand’ instead of ‘4000.’ Be sure to include the relevant placeholder words like ‘hundred,’ ‘thousand,’ ‘million,’ etc., to ensure clarity.

Exceptions and Special Cases

While the above rules provide a solid foundation, there are exceptions and special cases to be aware of when writing numbers in words. Let’s explore some of these exceptions:

Fractions and Decimals

When expressing fractions and decimals, use numerals. For example, write ‘0.5’ instead of ‘zero point five’ and ‘3/4’ instead of ‘three quarters.’ These cases involve specific mathematical notations that are best represented using numerals.

Numbers with Hyphens or Slashes

When numbers include hyphens or slashes, combine words and numerals. For example, write ‘twenty-one’ instead of ‘twenty-1’ and ‘eighty-nine’ instead of ’89.’ These hyphenated numbers provide clarity and are often preferred over numerals.

Numbers Used in Specific Contexts

Some numbers have specific conventions when used in certain contexts, such as dates, addresses, and measurements. For instance, ‘July 4th’ is written as a numeral (‘4’) followed by ‘th.’ Similarly, addresses like ‘123 Elm Street’ use numerals for the street number. Familiarize yourself with these conventions to ensure accurate representation.

Mastering the Number ’45’

The number ’45’ can pose a specific challenge when it comes to consistency in writing. It is essential to understand the problem with inconsistent use of numerals and words before delving into the advantages of correctly writing ’45’ in words.

Explaining the Problem with Inconsistent Use

Using numerals (’45’) and words (‘forty-five’) interchangeably can disrupt the flow and coherence of your writing. Inconsistent use can confuse readers and hinder comprehension. To illustrate, let’s compare the incorrect and correct usage of ’45.’

Demonstration of Incorrect Usage: ’45’ vs. ‘forty-five’

Here’s an example that demonstrates inconsistent usage:

“I have 45 apples in my basket, but I gave forty-five to my friend.”

In this sentence, one instance of ’45’ is written in numerals, while the other is spelled out with words. This inconsistency can distract readers and create unnecessary confusion.

Advantages of Using Words to Write ’45’ Correctly

Now that we understand the problem of inconsistency, let’s explore the advantages of consistently writing ’45’ in words (‘forty-five’):

Enhanced Readability

Using words to write ’45’ improves readability. Words are generally easier to process and comprehend compared to numerals. By consistently writing ’45’ in words, readers can quickly understand the intended meaning without any ambiguity.

Clarity in Professional Communication

In professional communication, clarity is crucial. Using words to express numbers consistently helps convey information accurately. Whether it’s a report, an email, or any professional document, writing ’45’ as ‘forty-five’ ensures that your message is clear and effectively understood by your audience.

Improved Adherence to Writing Style Guides

Many writing style guides, such as the Associated Press (AP) Stylebook and the Chicago Manual of Style, provide guidelines for writing numbers. Consistently following these guidelines demonstrates your attention to detail and adherence to established writing standards. Writing ’45’ in words aligns with these guidelines in most cases.

Examples of Correctly Writing ’45’ in Words

Here are a few examples of correctly writing ’45’ in words:

Reasons Why Properly Writing Numbers Matters

Writing numbers correctly, including ’45’ in words, has several important reasons and benefits. Let’s explore them in detail:

Avoiding Potential Confusion or Misinterpretation

Writing ’45’ in words eliminates the possibility of misreading the number as a different value. For example, ’45’ could mistakenly be read as ’54’ due to its visual similarity. By using words, such misinterpretations are entirely avoided.

Meeting Stylistic Guidelines and Expectations

Whether you are writing for an academic paper, a published article, or a business report, consistently writing ’45’ in words demonstrates your attention to detail and commitment to meeting expectations.
