A group of 9 people won 1/5 of a $4500 prize. How much money did each person in the group win?

The total amount won by the group is 1/5 * $4500 = $<<1/5*4500=900>>900.

So, each person in the group won $900 / 9 = $<<900/9=100>>100. Answer: \boxed{100}.

To find out how much money each person in the group won, you need to divide the total prize money by the number of people in the group.

Step 1: Calculate the share of the prize money won by the group.
The group won 1/5 of the $4500 prize money, which can be calculated as follows:
(1/5) * $4500 = $900

Step 2: Divide the share of the prize money by the number of people in the group.
Since there are 9 people in the group, you can divide the share of the prize money by 9:
$900 / 9 = $100

Therefore, each person in the group won $100.

To find out how much money each person in the group won, we need to divide the total prize money by the number of people in the group.

First, let's find out how much the group won. The group won 1/5 of the $4500 prize money, which means they won:

1/5 * $4500 = $900

Now, we need to divide this amount by the number of people in the group, which is 9. So, to find out how much money each person in the group won, we divide $900 by 9:

$900 / 9 = $100

Each person in the group won $100.
