Technically, yes. But frequently both elements of a ratio would be multipled up to get rid of the fraction.
So a ratio of 2 : 2.25 is valid, but one would multiply both by 4 to get the equivalent ratio 8 : 9.
A ratio involving a fraction is normally used only when there is a very good reason for the one of the elements of the ratio to be shown as a "round" number.
For example, a map scale would be given as "1 inch to 4.5 miles" rather than the equivalent "2 inches to 9 miles" so as to ensure that one of the elements of the ratio is 1.
