What is a Mixed Number?

A mixed number is a combination of a whole number and a proper fraction. It is written in the form of a whole number followed by a fraction. For example, $7 \frac{1}{10}$ is a mixed number where 7 is the whole number and $\frac{1}{10}$ is the proper fraction.

Why Convert Mixed Numbers to Improper Fractions?

Converting mixed numbers to improper fractions is an essential skill in mathematics, particularly in algebra and calculus. Improper fractions are easier to work with and can be used to simplify complex calculations. In this article, we will learn how to convert mixed numbers to improper fractions using a step-by-step approach.

Step 1: Identify the Whole Number and the Proper Fraction

To convert a mixed number to an improper fraction, we need to identify the whole number and the proper fraction. In the example $7 \frac{1}{10}$, the whole number is 7 and the proper fraction is $\frac{1}{10}$.

Step 2: Multiply the Whole Number by the Denominator

The next step is to multiply the whole number by the denominator of the proper fraction. In this case, we multiply 7 by 10, which gives us 70.

Step 3: Add the Product to the Numerator

Now, we add the product obtained in Step 2 to the numerator of the proper fraction. In this case, we add 70 to 1, which gives us 71.

Step 4: Write the Result as an Improper Fraction

Finally, we write the result obtained in Step 3 as an improper fraction. In this case, we write $\frac{71}{10}$ as the improper fraction equivalent of $7 \frac{1}{10}$.

Example 1: Converting $3 \frac{2}{5}$ to an Improper Fraction

Let's apply the steps we learned earlier to convert $3 \frac{2}{5}$ to an improper fraction.

• Identify the whole number and the proper fraction: The whole number is 3 and the proper fraction is $\frac{2}{5}$.
• Multiply the whole number by the denominator: 3 × 5 = 15.
• Add the product to the numerator: 15 + 2 = 17.
• Write the result as an improper fraction: $\frac{17}{5}$.

Example 2: Converting $4 \frac{3}{8}$ to an Improper Fraction

Let's apply the steps we learned earlier to convert $4 \frac{3}{8}$ to an improper fraction.

• Identify the whole number and the proper fraction: The whole number is 4 and the proper fraction is $\frac{3}{8}$.
• Multiply the whole number by the denominator: 4 × 8 = 32.
• Add the product to the numerator: 32 + 3 = 35.
• Write the result as an improper fraction: $\frac{35}{8}$.

Tips and Tricks

• When converting mixed numbers to improper fractions, make sure to multiply the whole number by the denominator and add the product to the numerator.
• Use a step-by-step approach to ensure accuracy.
• Practice converting mixed numbers to improper fractions to become more confident and proficient.
