Adjectives are mainly words which tell us more about nouns and pronouns. Their function is to tell us what kind, which ones, how many, what position or what colour. To put it more precisely, a word accompanying a noun to describe or point out, the person, animal, place or thing which the noun names, or to tell the number or quantity is called an adjective.

He was first in the race. (What position?)

Note: When a numeral is used as a noun, the cardinal, like the pronominal adjectives, takes no article. On the other hand, the ordinal uses the article.

When a numerical expression is used as an adjective, the singular form should be used. So, the plural form should be changed to appropriate singular form before the noun.
