## How to Spell 30

The number 30 is spelled as ‘thirty’. This two-syllable word combines the words ‘three’ and ‘ty’, the latter of which denotes a multiple of ten. Therefore, when we spell out the number, it becomes t-h-i-r-t-y.

## Spelling Details and Variations

There are no notable spelling variations for the number 30. However, when it comes to the ordinal form, the spelling changes slightly. To spell the ordinal number for 30, you add “-th” at the end to get ‘thirtieth’. The numerically expressed ordinal number is 30th.

## When to Spell Out 30 and When to Use the Numeral

Generally, whole numbers less than one hundred are spelled out in text, which means ‘thirty’ should be spelled out rather than using the numeral ’30’. However, the numeral should be used in technical contexts, when paired with units of measurement, or in graphical representations. If ’30’ appears at the beginning of a sentence, it should be spelled out.

## Practical Examples in Sentences

## Special Considerations

In financial contexts, ’30’ is typically used in numerals, as when describing a sum of money, such as \$30.00, to provide clear and precise information. In statistical contexts, the number ’30’ is considered a significant sample size, often referred to as ‘n=30’. In technical or scientific writing, one would use the numeral, like “30% of the sample”, for clarity and conciseness.

## Conclusion

The number 30 is integral to both everyday life and specific contexts, such as financial, technical, and statistical writing. Understanding when to spell it out and when to use the numeral is essential for clear communication. Thirty may just be another round number, but it plays a significant role in various domains, from marking significant birthdays to constituting baseline sample sizes in research.
