Final answer:
Comparisons of equality using nouns are formed by placing the word 'as' before a singular noun and then the word 'as' after them.
Step-by-step explanation:
To form comparisons of equality using nouns, you place the word as before a singular noun and then the word as after them. For example, 'She is as tall as a tree.' In this sentence, 'as tall as' is used to compare the height of the person to the height of a tree.
For example:
The book is as interesting as the movie.
Maria is as intelligent as her brother.
