Can 9/4 be written as more then one mixed number

yes it can be written as:

              1 5/4        and   2 1/4

if you want to put in more simplest terms you write it as 2 1/4.

        I hope this helps... :)

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
