Brief definition Mathematically, the ratio is defined as comparing two or more numbers that display their sizes about each other. A ratio tells how much of one quantity there is compared to another quantity. This math concept compares two quantities by division, with the dividend or number is divided, and the divisor or number is divided.
Lessons involving ratio begin in 6th grade. Here, they need to understand ratio concepts and use ratio reasoning to solve problems. 6th graders make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of importance on the coordinate plane. This topic is spirally discussed until 8th grade, where the focus of the tasks is about proportional relationships.
Importance of the Topic Ratio is an accurate and systematic manner of comparing quantities. This concept is fundamental to help us compare things logically and avoid biased decisions. Ratio provides the learners with an opportunity to discover and represent the relationship of two quantities — on how one value is bigger or smaller than the other. Also, ratio is a vital springboard for understanding proportion and proportional relationships. So it is better to understand ratio meaningfully because it is related to other math lessons.
Application of the Learned Topic in Life As we compare quantities in real-life, we are using the concepts of ratio without knowing it! When we bake bread, the ratio of the cups of flour and other dry ingredients must be accurate to come up with a perfectly moist bread. When we go on a long-distance drive, it is essential to know how many liters of gasoline is needed to arrive at the desired destination. These are just a few examples of how we can apply the ratio concepts to solve real-life problems.
