Oct 13, 2025 by orovajewels.com 84 views

Renaming fractions is an essential skill in mathematics, particularly in fractions and decimals. It involves expressing a fraction in an equivalent form with a different denominator. However, this process can be prone to errors if not done correctly. In this article, we will critique the reasoning behind the renaming of the fractions $\frac{3}{4}=\frac{9}{12}$ and $\frac{2}{3}=\frac{6}{12}$ and explain any mistakes made. We will also provide the correct renaming of these fractions.

The Importance of Renaming Fractions

Renaming fractions is crucial in mathematics because it allows us to compare and order fractions with different denominators. It also helps us to perform arithmetic operations with fractions, such as addition and subtraction. For example, if we want to add $\frac{1}{4}$ and $\frac{1}{6}$ , we need to find a common denominator, which is 12. We can then rewrite the fractions as $\frac{3}{12}$ and $\frac{2}{12}$ , and add them to get $\frac{5}{12}$ .

Critique of the Renaming of $\frac{3}{4}=\frac{9}{12}$

The given renaming of $\frac{3}{4}=\frac{9}{12}$ seems to be incorrect. To rename a fraction, we need to multiply both the numerator and the denominator by the same number. In this case, we can multiply both the numerator and the denominator of $\frac{3}{4}$ by 3 to get $\frac{9}{12}$ . However, this is not the only way to rename the fraction.

Mistake in the Renaming of $\frac{3}{4}=\frac{9}{12}$

The mistake in the renaming of $\frac{3}{4}=\frac{9}{12}$ is that it is not the simplest form of the fraction. To rename a fraction, we should aim to get the simplest form, which is the fraction with the smallest possible denominator. In this case, we can multiply both the numerator and the denominator of $\frac{3}{4}$ by 3 to get $\frac{9}{12}$ , but we can also multiply both the numerator and the denominator by 4 to get $\frac{12}{16}$ , which is a simpler form.

Correct Renaming of $\frac{3}{4}=\frac{9}{12}$

The correct renaming of $\frac{3}{4}$ is $\frac{12}{16}$ , which is a simpler form than $\frac{9}{12}$ .

Critique of the Renaming of $\frac{2}{3}=\frac{6}{12}$

The given renaming of $\frac{2}{3}=\frac{6}{12}$ seems to be incorrect. To rename a fraction, we need to multiply both the numerator and the denominator by the same number. In this case, we can multiply both the numerator and the denominator of $\frac{2}{3}$ by 4 to get $\frac{8}{12}$ , but we can also multiply both the numerator and the denominator by 3 to get $\frac{6}{9}$ , which is a simpler form.

Mistake in the Renaming of $\frac{2}{3}=\frac{6}{12}$

The mistake in the renaming of $\frac{2}{3}=\frac{6}{12}$ is that it is not the simplest form of the fraction. To rename a fraction, we should aim to get the simplest form, which is the fraction with the smallest possible denominator. In this case, we can multiply both the numerator and the denominator of $\frac{2}{3}$ by 4 to get $\frac{8}{12}$ , but we can also multiply both the numerator and the denominator by 3 to get $\frac{6}{9}$ , which is a simpler form.

Correct Renaming of $\frac{2}{3}=\frac{6}{12}$

The correct renaming of $\frac{2}{3}$ is $\frac{6}{9}$ , which is a simpler form than $\frac{6}{12}$ .

Conclusion

Renaming fractions is an essential skill in mathematics, but it can be prone to errors if not done correctly. In this article, we critiqued the reasoning behind the renaming of the fractions $\frac{3}{4}=\frac{9}{12}$ and $\frac{2}{3}=\frac{6}{12}$ and explained any mistakes made. We also provided the correct renaming of these fractions. The correct renaming of $\frac{3}{4}$ is $\frac{12}{16}$ , and the correct renaming of $\frac{2}{3}$ is $\frac{6}{9}$ .

Common Mistakes in Renaming Fractions

There are several common mistakes that people make when renaming fractions. These include:

Not simplifying the fraction: When renaming a fraction, we should aim to get the simplest form, which is the fraction with the smallest possible denominator.
Not multiplying both the numerator and the denominator by the same number: To rename a fraction, we need to multiply both the numerator and the denominator by the same number.
Not checking for equivalent fractions: Before renaming a fraction, we should check if there are any equivalent fractions with a smaller denominator.

Tips for Renaming Fractions

Here are some tips for renaming fractions:

Use the least common multiple (LCM): To rename a fraction, we can use the LCM of the numerator and the denominator to find the new denominator.
Simplify the fraction: Before renaming a fraction, we should simplify it to its simplest form.
Check for equivalent fractions: Before renaming a fraction, we should check if there are any equivalent fractions with a smaller denominator.

Real-World Applications of Renaming Fractions

Renaming fractions has several real-world applications, including:

Cooking: When cooking, we often need to rename fractions to convert between different units of measurement. For example, we may need to convert between cups and ounces.
Building: When building, we often need to rename fractions to convert between different units of measurement. For example, we may need to convert between feet and inches.
