## How Do You Know If A Proportion Is Correct?

“How can you determine if a proportion is accurate? Let’s explore the process of verifying the correctness of a proportion. To begin, suppose we have a proportion involving the number 5.4. To check its accuracy, we perform a multiplication of 5.4 by 5, resulting in 27. This same value of 27 should be obtained from both sides of the proportion. This method provides a practical and reliable way to confirm the correctness of a proportion calculation.”

Understanding Proportions and Ensuring Their Accuracy

Proportions are a fundamental concept in mathematics, and understanding how to ensure their accuracy is crucial. To determine if a proportion is true, we can use a method called “cross products.” This method involves multiplying the numerator of the first fraction by the denominator of the second fraction and vice versa. Let’s break down the process step by step:

- Identify the two fractions in the proportion.
- Take the numerator of the first fraction and multiply it by the denominator of the second fraction.
- Similarly, multiply the numerator of the second fraction by the denominator of the first fraction.
- Compare the two results obtained in steps 2 and 3.
- If the two results are equal, the proportion is true; if not, it is not true.

In the example provided, we have the following calculation:

Numerator of the first fraction (4) multiplied by the denominator of the second fraction (12) = 4 x 12 = 48.

Numerator of the second fraction multiplied by the denominator of the first fraction (missing information) = ?

To make the proportion true, we need to calculate the missing information in step 5 and ensure that it is also equal to 48. This process helps us confirm the accuracy of proportions in various mathematical problems.

**If the simplified fractions are the same**, the proportion is true; if the fractions are different, the proportion is false.Ratios are proportional **if they represent the same relationship**. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. To see this process in action, check out this tutorial!Hence, given terms **12 , 16 , 6 , 8 are in proportion**.
