Sometimes confused around how and when to usage a hyphen once writing the end numbers, either totality numbers or fractions? Be puzzled no an ext after you review today"s post.

Hyphens and Spelled-out Fractions
Fractions should constantly be hyphenated once they space adjectives or adverbs, together in They gained a one-third share and also The money is three-quarters gone. Opinions different on even if it is they have to be hyphenated once they space nouns, together in They obtained one-third that the money. By conventional rules the hyphenation, over there is no factor to hyphenate them; castle are merely noun compounds created of adjective + noun.
However, the hyphen is "heard" -- we perform not pronounce the elements of such compounds as unique words but slur lock together--and omission of the hyphen might conceivably mislead: I used to save all of my change in a bucket, yet I"ve invested three soldier of it. We suggest hyphenating fountain routinely. One can think of the hyphen together representing the division bar in a portion in figures.
The steed rounded the track five and also three-quarters times. Adjectival compound of a totality number and also a portion are not hyphenated throughout uneven they are complicated by another word, as in The horse dropped at the one-and-one-quarter-mile mark.
Hyphens with phrases include numbers
Phrases containing numbers follow a couple of special hyphenation conventions.
Exceptions from standard rules
Five hundred men modifies men v the adjective + noun compound five hundred, and also normally together a compound would certainly be hyphenated. But unless the number compound is complicated by an additional word or phrase, together in later examples, spelled-out numbers carry out not follow typical hyphenation rules when they change a noun, no matter how numerous words the takes to spell them out: five hundred and thirty-six men.
Ten-dollar loss and two-hundred-million-dollar loss follow typical rules; the spelled-out numbers are like any type of other words supplied in compounds. When numbers are used, one often sees a hyphen wherein there is no justification because that it: $10-loss. This is together incorrect as ten-dollar-loss.
But over there is one exception to the standard rules.
When a large round amount of money preceded by the dollar sign (or a international sign or abbreviation such together £ or DM) is partially in figures and also partly spelled out, together in $200 million, it traditionally does not gain a hyphen as an adjective: $200 million loss. One does watch the hyphen occasionally, and also though that can"t be referred to as wrong, due to the fact that it is over there if the number is totally spelled out, that is troublesome; possibly the eye is somehow conscious that there space invisible hyphens through the adjectival elements represented by $200 and wants all the hyphens in the link to it is in invisible. Hyphens room used, and also required through the eye, if together a link is an unified with one more word or expression that requirements hyphenation: $200-million-plus loss, $200-million-per-quarter loss.
Similarly, adjectival link of figures + percent are traditionally not hyphenated unless they are part of bigger compounds: 23 percent increase, 23-percent-a-year increase. This holds also when over there is no invisible hyphen in the figure and our speculation about the consistency-loving eye division down, together in 10 percent increase.
