2. Five divided by the sum of \( a \) and \( b \)

Did you know that division can be traced back to ancient civilizations? The Babylonians used a base-60 system, developing methods to solve equations that are surprisingly similar to our division today! Imagine ancient scholars huddling over clay tablets, refining methods that would eventually lead to how we express concepts like “five divided by the sum of \( a \) and \( b \)”! In real-world scenarios, this formula can come in handy! Think about it: if you’re sharing five cookies among friends, where \( a \) is the number of friends you have, and \( b \) is the number of friends who can eat cookies, it helps you figure out how many cookies each person gets! It's division simplified for daily life, making sharing treats a whole lot easier. Keep it sweet!
