In this lesson, you will learn what a ratio is and why we use ratios in math. You will also learn how to represent a ratio as a fraction and also how to write a ratio in colon notation. A ratio is a comparison between two numbers. A proportion is when two ratios are equal to one another. For example, if we have a room with 10 boys and 5 girls, we might write the ratio of boys to girls as 10:5, or as a fraction, 10/5. We can then simplify this ratio just like we simplify any fraction down to the simplest ratio, 2/1 in this case. This ratio indicates that in this room there are 2 boys for every 1 girl. We use ratios in all math subject areas to solve a wide variety of problems.
