Definition
Equivalent ratios are two or more ratios that represent the same relationship between quantities, even though the numbers in the ratios may be different. Equivalent ratios can be created by multiplying or dividing both terms of a ratio by the same nonzero number.
For example, the ratios 2:3, 4:6, and 6:9 are equivalent because they all describe the same proportional relationship. If both terms of 2:3 are multiplied by 2, the result is 4:6; if both are multiplied by 3, the result is 6:9.
Understanding equivalent ratios helps students recognize and work with proportional relationships. Students can find equivalent ratios by using multiplication or division, ratio tables, double number lines, diagrams, or equations. For example, if 3 notebooks cost $6, an equivalent ratio shows that 6 notebooks would cost $12. Both situations have the same relationship between the number of notebooks and their cost.
Equivalent ratios are important because they provide a foundation for later topics such as proportions, unit rates, percentages, scale drawings, and similar figures. Students should learn not only how to generate equivalent ratios but also how to determine whether two given ratios are equivalent.
This topic aligns with U.S. Common Core State Standards (CCSS), particularly in the following areas:
- CCSS.MATH.CONTENT.6.RP.A.1 – Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
- CCSS.MATH.CONTENT.6.RP.A.3 – Use ratio and rate reasoning to solve real-world and mathematical problems.
- CCSS.MATH.CONTENT.6.RP.A.3.A – Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot pairs of values on the coordinate plane. Students also use tables to compare ratios.
Learning equivalent ratios therefore develops students’ ability to identify proportional relationships and apply ratio reasoning to practical and mathematical situations.

Frequently Asked Questions
Equivalent ratios are ratios that compare quantities in the same relationship, even though they use different numbers. For example, 2:3 and 4:6 are equivalent because both parts of 2:3 were multiplied by 2.
Multiply or divide both parts of a ratio by the same nonzero number.
For example, starting with 3:5:
Multiply both numbers by 2 → 6:10
Multiply both numbers by 3 → 9:15
Therefore, 3:5, 6:10, and 9:15 are equivalent ratios.
You can simplify the ratios or use cross multiplication. If both ratios simplify to the same ratio, or if their cross products are equal, they are equivalent.
For example, 4:6 and 10:15 are equivalent because both simplify to 2:3.
