Let's solve each division word problem step by step.

Problem 1:
Janet has 48 boxes of crayons. She has 480 crayons in total. How many crayons are there in each box?
#### Solution:
To find the number of crayons in each box, we need to divide the total number of crayons by the number of boxes.
\[
\text{Number of crayons per box} = \frac{\text{Total number of crayons}}{\text{Number of boxes}}
\]
\[
\text{Number of crayons per box} = \frac{480}{48}
\]
Perform the division:
\[
480 \div 48 = 10
\]
So, there are
10 crayons in each box.

Problem 2:
Green has 11 boxes of erasers. She has 485 erasers in total. How many erasers are there in each box?
#### Solution:
To find the number of erasers in each box, we need to divide the total number of erasers by the number of boxes.
\[
\text{Number of erasers per box} = \frac{\text{Total number of erasers}}{\text{Number of boxes}}
\]
\[
\text{Number of erasers per box} = \frac{485}{11}
\]
Perform the division:
\[
485 \div 11 = 44 \text{ R } 1
\]
This means there are
44 erasers in each box, with a remainder of 1 eraser. Since the problem asks for the number of erasers per box, we can say:
\[
\text{Number of erasers per box} = 44 \text{ (with 1 eraser left over)}
\]
So, there are
44 erasers in each box.

Problem 3:
Amelia has a set of 180 books which she wishes to share it with 15 of her friends. How many books will each friend receive?
#### Solution:
To find the number of books each friend will receive, we need to divide the total number of books by the number of friends.
\[
\text{Number of books per friend} = \frac{\text{Total number of books}}{\text{Number of friends}}
\]
\[
\text{Number of books per friend} = \frac{180}{15}
\]
Perform the division:
\[
180 \div 15 = 12
\]
So, each friend will receive
12 books.

Problem 4:
Sophie has to write 1500 emails. She can email 25 every day. How many days will Sophie take to email all the 1500 then?
#### Solution:
To find the number of days Sophie will take to write all the emails, we need to divide the total number of emails by the number of emails she can write per day.
\[
\text{Number of days} = \frac{\text{Total number of emails}}{\text{Emails per day}}
\]
\[
\text{Number of days} = \frac{1500}{25}
\]
Perform the division:
\[
1500 \div 25 = 60
\]
So, Sophie will take
60 days to write all the emails.

Problem 5:
Jessica is inviting 32 friends to a party. She has 2,880 cookies. How many cookies will each friend get?
#### Solution:
To find the number of cookies each friend will receive, we need to divide the total number of cookies by the number of friends.
\[
\text{Number of cookies per friend} = \frac{\text{Total number of cookies}}{\text{Number of friends}}
\]
\[
\text{Number of cookies per friend} = \frac{2880}{32}
\]
Perform the division:
\[
2880 \div 32 = 90
\]
So, each friend will receive
90 cookies.
