What is an Equivalent Ratio?
Equivalent ratios are the kind of ratios that remain the same when we compare them. We compare multiple ratios alongside each other to check whether they are equivalent or not. It can be shown easily by an example, i.e.
If we want to get a ratio that is equivalent to an already given ratio, we need to multiply or divide both of the terms of the given ratio by the same non-zero number.

Equivalent Ratios and Equivalent Fractions
In order to find the equivalent ratios of a given ratio, we write the ratio as a fraction and then multiply and divide for them to be compared. The ratio can also be expressed as a fraction. Let a:b, be a ratio, then a/b can be the fraction form. It can also be compared to two or more equivalent ratios in the form of equivalent fractions.
How Do We Find the Equivalent Ratios of a Given Ratio?
The step-by-step process to find the equivalent ratios of a given ratio is given below:
We can find the two equivalent ratios by using multiplication and division as tools
If we want to get a ratio that is equivalent to an already given ratio, we need to multiply or divide both of the terms of the given ratio by the same non-zero number.
In order to find the equivalent ratios of a given ratio, we write the ratio as a fraction and then multiply and divide for them to be compared.
Ratio Multiplication
Ratio multiplication is the mathematical operation of multiplying two ratios or more by one another. Let’s understand it by examples.
Solved Examples
Example 1. Give two equivalent ratios of
Ans: It begins with finding the equivalent ratio of
The first step is to represent the ratio as a fraction, =
Now we multiply it by the same number.
(one equivalent ratio),
So,
We can also find the equivalent ratio of
Here also, the first step is to represent the ratio as a fraction,
(another equivalent ratio)
So, 6: 165 is an equivalent ratio of
We can see that the equivalent ratios of
Example 2. Find the two equivalent ratios of
Ans: It begins with finding the equivalent ratio of
The first step is to represent the ratio as a fraction.
Now, we multiply it by the same number.
In order to find another equivalent ratio, we multiply again with another number.
The first step is to represent the ratio as a fraction.
Now, we multiply it by the same number.
We can see that the equivalent ratios are
Note: We can see that the division method was not applied in this case to get the answer in integer form, which is due to the G.C.F. of 4, and 5 is 1. Hence, 4 and 5 is not divisible by any other number other than 1.
Example 3. If the ratio is
Ans: It begins with finding the equivalent ratio of
The first step is to represent the ratio as a fraction.
Now we multiply it by the same number.
Equivalent Ratio of 8:15
Now, let’s see the equivalent ratio of 8:15. Below are the step to find out the ratio:
In order to find the equivalent ratios of 8:15 by multiplication, we must multiply the numbers by 2, i.e. 8x2 : 15x2
Therefore, the equivalent ratio now is 16:30.
Practice Questions
Q1. Write the equivalent ratio of 3:9
Ans: 6:18
Q2. Write the equivalent ratio of 7:8
Ans: 14:16
Q3. Write two equivalent ratios for 5:7
Ans: 10:14 and 15:21

Finding an Equivalent Ratio
Summary
Ratios that are identical when compared are referred to as equivalent ratios. To determine whether two or more ratios are equivalent, they can be put side by side. An equivalent ratio is, for instance, 1:2 and 2:4. These ratios remain the same even after being changed via mathematical tools. The ratios can be represented using a fraction and thus modified by these tools. There can be multiple equivalent ratios based on the change in values and the tool used.
FAQs on Understanding Equivalent Ratio with Solved Examples
1. What is a visual method?
Let us suppose we have an image where each of the ratios
2. Define equivalent ratios in simple terms.
Ratio can also be represented as a fraction. It is a very similar concept to the equivalent fractions. The ratios are obtained by multiplying or dividing the given ratio which has the same value as the given ratio.
E.g. 3:6 is a ratio and to get an equivalent ratio, convert it to a fraction of
Now, on multiplying the numbers by 2, we get
3. What is the need for equivalent ratios?
Place value supports us in making judgments that we use in our daily lives, such as costs, weight, distances, and time. In this context, equivalent ratios help us make comparisons between different items. Our number system is based on a ten-point scale. The term "base ten" refers to our number system's base of 10. We divide our numbers into groups of ten.
