How can you tell if two ratios are equivalent?
How can you tell if two ratios are equivalent? By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio. For example, if the ratios are 3:5 and 9:15, multiply 3 by 15 and 5 by 15 to get 45:75.
How do you find equivalent ratios?
Summary:
- You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount.
- You only multiply or divide, never add or subtract, to get an equivalent fraction.
- Only divide when the top and bottom stay as whole numbers.

What is ratio in math?
In Mathematics, a ratio compares two quantities named as antecedent and consequent, by the means of division. For example, when we cook food, then each ingredient has to be added in a ratio. Thus, we can say, a ratio is used to express one quantity as a fraction of another quantity.
What is the symbol for ratio?

When the comparison of two different ratios is same, the such ratios are called?
When the comparison of two different ratios is same, the such ratios are called equivalent ratios. For example, 1:2 and 3:6 are equivalent.
Can a ratio be expressed as a fraction?
We can also express the ratio as a fraction. If a:b, is a ratio, then a/b is its fraction form. Thus, we can easily compare two or more equivalent ratios in the form of equivalent fractions.
Is a given ratio equivalent to a simplified form?

How are Proportional Quantities Described by Equivalent Ratios?
A set of equivalent ratios represent proportional quantities. For example, we can say that 2:3 and 4:6 are in proportion. Proportion is nothing but the equality of ratios. This is how proportional quantities can be described by equivalent ratios.
How to Find Missing Numbers in Equivalent Ratios?
To find missing values in equivalent ratios, we have to first find the multiplying factor by equating the values of antecedents and consequents, and then we find the missing number. For example, if it is given that 1:4 and x:16 are equivalent ratios and we have to ding the missing value x. Here, the values of consequents are known to us, i.e 4 and 16. We multiply 4 by 4 to get 16. So, 4 us the multiplying factor in this case. So, we will multiply the antecedent of the first ratio 1 by 4 to find x. Therefore, the value of x is 4 such that 1:4 and 4:16 are equivalent ratios.
How to find unit rate?
Unit rates and equivalent ratios are related to each other. Unit rates can be found by using the concept of equivalent ratios. For example, if it is given that a car covers 70 miles in 2 hours. In the ratio, it can be expressed as 70:2. We can find the unit rate (distance covered in 1 hour), by finding the equivalent ratio of 70:2 such that 2 will be reduced to 1. For that, we need to multiply both the terms by 2 to get 35:1. This is the required unit rate. Similarly, we can also find equivalent ratios from a given unit rate by multiplying the terms with a natural number. This is how unit rates and equivalent ratios are related to each other.
What is the required value of x in 2:3?
Therefore, 2:3 and 10:15 are equivalent ratios, and the required value of x is 15.
What is the formula for 2:3?
Solution: It is given that 2:3 = 10:x. It means that we have to multiply 2:3 with a natural number such that the answer will be of form 10:x, where x is any natural number. Let us look at the antecedents 2 and 10. If we multiply 2 by 5, we get 10. It means we will have to multiply 3 with 5.
What is equivalent ratio?
Equivalent ratios are ratios that describe the same rate or make the same comparison. They are a result of the fact that ratios are scalable, meaning that they can be multiplied or divided by a constant to yield the same relationship, expressed in larger or smaller quantities. For example, there are 2 circles and 3 squares in the figure below.
How are equivalent ratios related to proportions?
Equivalent ratios are related to proportions in that proportions are a statement that two ratios are equal, making the ratios involved in any proportion, equivalent ratios.
What is the ratio of circles to squares?
The ratio of circles to squares can be written as 2:3. If there were twice as many squares, and twice as many circles, the ratio of circles to squares could be written as 2 (2):3 (2) = 4:6. Although there are more circles and squares, the ratio of circles to squares remains constant, so 2:3 and 4:6 are equivalent ratios.
Is a ratio equivalent to a factor of 2?
Since either of the ratios can be scaled by a factor of 2 to equal the other, they are equivalent ratios.

What happens when you multiply the same ratio?
So when you multiply both parts of a ratio by the same number, you make an equivalent ratio. All we’re really doing is making equivalent fractions, which are two different fractions that are equal. We could, in fact, multiply the numerator and denominator by any number and get an equivalent fraction.
Why are ratios 60/1 and 120/2 equivalent?
In fact, they’re called equivalent ratios, which are ratios that express the same relationship between two numbers. The ratios 60/1 and 120/2 are equivalent because the relationship between the two parts of the ratios didn’t change.
