Final answer:
Keyma would need 436 boxes to fit 8283 cookies with boxes holding 19 cookies each.
Step-by-step explanation:
If Keyma had 8283 cookies and she put them in boxes of 19, we need to divide the total number of cookies by the number of cookies that can fit in each box. We perform the division 8283 ÷ 19 to find the total number of boxes needed.
When we do the division, we get:
8283 ÷ 19 = 436 with a remainder.
This means Keyma would have 436 full boxes, and there would be extra cookies that wouldn't fit in another full box. Since they don't fit into a full box of 19, we don't count these as another full box.
Therefore, Keyma would have 436 boxes.
