A ratio is like a special way to compare two numbers. 📊 It tells us how many times one number can fit into another. Imagine if you got only half as many cookies as your sister. You'd know it's not fair! 😡 That's a ratio: 1 to 2, or 1/2. It means you got one cookie for every two your sister got.
Ratios can be written with a colon (1:2), as words (1 to 2), or as fractions (1/2). The first number shows how many times the second number fits in. If the first number is bigger, like 2:1, it means 2 can fit 1, two times. Ratios can have more than two parts too!
We use ratios in lots of things! 🍰 In baking, for screens, maps, and even to talk about the chances of something happening. If you needed 5 cakes, and the recipe says you need a 1:2:3 ratio of butter, sugar, and flour, you'd know how much of each to use!
Screen ratios tell us about the shape of screens and videos. They're like the width compared to the height. Different screens have different ratios, like widescreen (16:9) or old TVs (4:3). Knowing these ratios helps us make things fit nicely on screens! 📺📱🎥
