They used fractions as a means to divide resources, like land and food, and they had unique ways to represent these fractions using symbols. It wasn't until the Middle Ages that the concept of fractions evolved into what we use today, which makes math history quite fascinating! In today's world, fractions play a vital role in various real-world applications. From cooking to construction, understanding fractions can be crucial. For instance, when following a recipe, if you need to double or halve the ingredients, you'll often work with fractions. In construction, measuring materials frequently requires fraction operations to ensure accuracy. It’s all about applying those fractions in your everyday life!
