To find out how many apples Olivia has in each basket and how many are left over, we need to divide the total number of apples by the number of baskets.
Olivia picked 482 apples and divided them into 4 baskets. We can perform the division:
\[ 482 \div 4 = 120 \]
Next, we can confirm by multiplying the quotient by the number of baskets:
\[ 120 \times 4 = 480 \]
Now, we subtract this result from the total apples to find out how many are left over:
\[ 482 - 480 = 2 \]
So, each basket contains 120 apples and there are 2 apples left over.
Final Answer: Each basket contains 120 apples, and 2 apples are left over.
