Jim has 1/3 as many goldfish as Hannah. Hannah has 5 times as many goldfish as Ping. If Ping has 15 goldfish, how many goldfish does Jim have?

15 X 5 = 75

75 / 3 = 25

Jim has 25 goldfish.

To find out how many goldfish Jim has, we need to follow the steps of the problem.

Let's start with Ping. The problem tells us that Ping has 15 goldfish.

Next, we are told that Hannah has 5 times as many goldfish as Ping. To find out how many goldfish Hannah has, we multiply the number of goldfish Ping has by 5. So, 15 x 5 = 75. Therefore, Hannah has 75 goldfish.

Now, we need to determine how many goldfish Jim has. The problem states that Jim has 1/3 as many goldfish as Hannah. To find out how many goldfish Jim has, we multiply the number of goldfish Hannah has by 1/3. So, 75 x 1/3 = 25.

Therefore, Jim has 25 goldfish.
