To convert the mixed number 3 8/13 into fraction form, you can follow a simple mathematical process. This process can be very helpful for those who are looking to work with fractions, whether in math class or in everyday situations. In this article, we’ll break down the steps you need to take to transform the mixed number into an improper fraction, making it easier to work with in calculations.
Understanding Mixed Numbers and Improper Fractions
Before we dive into the conversion process, it's important to understand the terms involved.
What is a Mixed Number? 🤔
A mixed number consists of a whole number and a proper fraction combined. For example, in the mixed number 3 8/13, the whole number is 3, and the fraction is 8/13.
What is an Improper Fraction? 📈
An improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number). For instance, 38/13 is an improper fraction since 38 is greater than 13.
Steps to Convert Mixed Number to Improper Fraction
Let’s break this down step by step:
Step 1: Multiply the Whole Number by the Denominator
In the case of 3 8/13, the whole number is 3, and the denominator of the fraction is 13. You will multiply these two together:
[ 3 \times 13 = 39 ]
Step 2: Add the Numerator
Now, take the result from Step 1 and add the numerator of the fraction (which is 8):
[ 39 + 8 = 47 ]
Step 3: Write the Result as an Improper Fraction
The result from Step 2 will be the new numerator, while the denominator remains the same. Therefore, you can write it as:
[ \frac{47}{13} ]
So, the mixed number 3 8/13 converts to the improper fraction 47/13.
Summary of the Conversion Process 📝
Step | Calculation | Result |
---|---|---|
Multiply | 3 x 13 | 39 |
Add Numerator | 39 + 8 | 47 |
Write Improper Form | 47/13 | 47/13 |
