Unit 12 Punctuation Abbreviations and Numbers Lesson 89 Solutions

Review the following solutions for exercises related to symbols, short forms, and numerical representations. Carefully follow each step to fully understand the proper usage and formatting rules.

For correct usage of abbreviations, ensure you apply the rules of punctuation consistently. For instance, periods are essential when shortening words like “Dr.” or “Mr.” but are not necessary for acronyms such as “USA” or “FBI.” Double-check your work to avoid any unnecessary punctuation marks.

When working with figures and their written equivalents, focus on the clarity of your expression. Writing numbers correctly in a sentence is crucial for accuracy. For example, use numerals for values 10 and above, and write out smaller numbers unless a specific rule applies.

Practice these concepts regularly to improve precision in both written and verbal communication. The more you reinforce these patterns, the more natural it will become to apply them correctly in your exercises and real-life writing.
