Answer:it is 27.999 repeated so you should always round down not up
First, lets find how much is 1/9 of the total fish is.
63 / 9 = 7 is 1/9 of the total fish.
Second, lets find how much 4/9 of the total fish is.
7 * 4 = 28 is 4/9 of the total fish.
There are 28 guppies out of the 63 fish.
Best of Luck!
