Answer:
1/5 of the prize money each
Step-by-step explanation:
If there are 5 siblings and the money is being distributed equally between the five of them, each sibling would get 1/5 of the prize money.
To understand this lets think of the prize as 1 whole. If we divided 1 whole into 5 equal parts, each part would be 1/5, or you can think of it as "1 out of 5".
