7th Grade Math Worksheets Proportions are a great way to help your students practice their proportional reasoning. There are 11 worksheets in this package, and each one has a different proportion problem to solve. Some of the problems include figuring out how many jars of jellybeans fit in a jar that is 10 inches wide and 6 inches high, finding the size of a triangle that is 3 inches wide, and counting how many rainbows are in a rainbow that is 5 feet long.              Learn how to solve proportion problems with these 7th Grade Math Worksheets Proportions!

Summary: A proportion is an assertion that two ratios are equivalent. Proportion is an equalization that explains two ratios are equivalent because they have the same values. It defines the parallelism of the ratios. We can write proportions as equivalent fractions (a/b = c/d) or equal ratios (a : b = c ; d). Understanding the concept of ratios and proportions is imperative because it is the foundation of various mathematic and scientific ideas and conceptions.

### What is Proportions in Math?

In the mathematical world, a proportion is an assertion that two ratios are equivalent. We can write it as equivalent fractions (1/4 = 5/20) or equal ratios (1 : 4 = 5 : 20). The term "equivalent" means we can multiply or divide one scale by another fixed value to create the other. Based on the previous example, we could multiply 1:4 by five (5) or divide 5/20 by 5.

1 : 4 = (1 x 5) : (4 x 5) = 5 : 20

5 : 20 = (5 ÷ 5) : (20 ÷ 5) = 1 : 2

Based on the example, we can conclude the ratios are proportional since the factor of five (5) link the ratios. There are four terms of proportion (a/b = c/d or a:b = c:d). The a and d are "extremes", and b and c are "means". In proportional ratios, the results of the means are the same as the extremes' results. Based on the above example, the results of (1 x 20) and (4 x 5) are the same, 20. Mastering how to solve proportions will help students to prepare themselves for algebra.

### What is Ratio in Math?

According to Khan Academy, the ratio is a comparison of two elements. We can write it as b/c or b:c. The "a" is the antecedent (prior), and the "b" is the consequent (later). A real-life example of using ratio is when you want to make double portions of a recipe. In mathematics, "equivalent ratio" means a ratio with an identical value. Ratios appear to help humans make a comparison. We can shorten them to the minimum to achieve simplicity. We can write ratios in two techniques, part to part or part to whole. To write it, you should pay attention to these details:

1. Settle whether it is part of part or part to whole.
2. Decide the "part" and the "whole".
3. Put values to the ratio.
4. Shorten them into an integer-to-integer rate.

### How to Teach Proportions?

Without realizing it, we often apply the proportions in our daily life. Hence, learning about them is necessary for the students. The teacher should give the students a fun teaching experience for the students. A proper learning strategy would improve the student's understanding of the material. Based on David Ben-Chaim from the Israel Institute of Technology, the teacher should ensure the teaching should include theoretical and practical knowledge for balance learning. This teaching strategy will allow the students to learn mathematics in a real-life context and offer creativity and teaching freedom to the teachers.

Teachers can use the "equivalent rates table" to introduce the students to proportional reasoning. Give the students easy numbers first and demonstrate a real-life example to make them understand easier. As the students get used, the teachers can level up the tables. After mastering the tables, the students can practice with the word problems. Assign them the problems and let them think and discuss them. This learning progress will help them to prepare for facing algebra.

### Why Should We Learn Proportions?

In mathematics, fractions are the foundation of ratios and proportions. When we write a fraction as a:b, it is a ratio. Proportions are a situation where two ratios have the same value. Understanding the concept of ratios and proportions is imperative because it is the foundation of various mathematic and scientific ideas and conceptions. In real-life, ratios and proportions are common mathematical knowledge we can find easily. For example, we can use ratios to write a comparison of something. Proportions are necessary if we want to draw an accurate image of something. It also helps when we deal with money in business.

### What are the Types of Proportions?

Proportion is an equalization that explains two ratios are equivalent because they have the same values. It defines the parallelism of the ratios. There are three categories of proportions, direct, inverse, and continued proportion. Direct proportions explain the link between two numerical elements, which means the increase in one ratio will affect the other. These rules also apply when the quantity decrease. Inverse proportions define the connection between two ratios in which the growth of one side will lead to the reduction of the other. The same rules apply to the opposite as well. The decline of one part will affect the increase of the other. The continued proportions require us to convert the "means" to a singular number. For example, the first ratio is (ca : bc), and the second is (bc : bd). The results of the continued proportion would be "ca : bc : bd".
