Dividing by One-digit Numbers and Deducing Remainders

Example 1:

Liam has \(29\) candies. He wants to share them equally among his \(5\) friends, including himself. How many candies will each friend get, and how many will remain?

Solution Process:

Answer:

They will have \(7\) full boxes, and \(1\) cookie will be left.

Understanding remainders is crucial when dividing numbers, especially in real-world scenarios where exact division isn’t always possible. By dividing and then determining the remainder, you can make informed decisions and understand the distribution of items better. Practice regularly to become adept at deducing remainders swiftly and accurately!
