The way to put decimals in order is to line them up first. Then you compare each column
4.769
4.904
4.422
Since the first column is the same you move on to the next one. Four is the lowest so 4.422 goes first. 7 is smaller than 9 so 4.769 is next and 4.904 is last.
4.422
4.769
4.904 is the order they go in.
