Divide the total amount of envelopes by the number of envelopes you can fit into a carton:
[tex] 22500 \div 500 = \boxed{45} [/tex]
You would need 45 cartons to complete the task.
Since there are 22500 cartons, and each can hold 500 envelopes, the operation we need to do is a division.
We just do: [tex] 22500 [/tex] ÷ [tex]500[/tex], and we get [tex] 45 [/tex].
So the answer is: 45.
