To convert a decimal like 2.4 into a mixed number, we will walk through a simple process that involves understanding both the whole and fractional parts of the number. Whether you're a student learning about fractions or just want to refresh your knowledge, this guide will help you convert decimals into mixed numbers easily. Let's dive in! 🌊
Understanding Mixed Numbers
A mixed number consists of a whole number and a proper fraction. For instance, the mixed number (2 \frac{1}{2}) has a whole part of 2 and a fractional part of (\frac{1}{2}).
Important Note: A proper fraction is a fraction where the numerator (the top number) is less than the denominator (the bottom number).
Step-by-Step Conversion of 2.4
Step 1: Identify the Whole Number Part
The first step in converting 2.4 into a mixed number is to identify the whole number part.
- The whole number part of 2.4 is 2.
Step 2: Identify the Decimal Part
Next, we'll look at the decimal part of the number, which in this case is 0.4.
Step 3: Convert the Decimal to a Fraction
Now, we need to convert the decimal part (0.4) into a fraction. To do this, we follow these steps:
-
Recognize that 0.4 is the same as (\frac{4}{10}) since 4 is in the tenths place.
-
We can simplify this fraction. Both the numerator and denominator can be divided by 2:
[ \frac{4 \div 2}{10 \div 2} = \frac{2}{5} ]
Step 4: Combine Whole and Fractional Parts
Now that we have the whole number and the fractional part, we can combine them.
-
Thus, (2.4) can be expressed as a mixed number:
[ 2.4 = 2 \frac{2}{5} ]
Final Result
Therefore, the decimal number 2.4 as a mixed number is
2 ( \frac{2}{5}.
More Examples of Converting Decimals to Mixed Numbers
Understanding the process is crucial, so let's explore a few more examples to solidify our knowledge!
Example 1: Converting 3.6
-
Whole number: 3
-
Decimal part: 0.6, which converts to (\frac{6}{10} = \frac{3}{5}) after simplification.
-
Mixed number:
[ 3.6 = 3 \frac{3}{5} ]
Example 2: Converting 4.75
-
Whole number: 4
-
Decimal part: 0.75, which converts to (\frac{75}{100} = \frac{3}{4}) after simplification.
-
Mixed number:
[ 4.75 = 4 \frac{3}{4} ]
Example 3: Converting 1.2
-
Whole number: 1
-
Decimal part: 0.2, which converts to (\frac{2}{10} = \frac{1}{5}) after simplification.
-
Mixed number:
[ 1.2 = 1 \frac{1}{5} ]
Summary of Examples in a Table
To help visualize our examples, here’s a table summarizing the conversions:
<table> <tr> <th>Decimal Number</th> <th>Whole Number</th> <th>Decimal Part</th> <th>Mixed Number</th> </tr> <tr> <td>2.4</td> <td>2</td> <td>0.4 = \frac{2}{5}</td> <td>2 \frac{2}{5}</td> </tr> <tr> <td>3.6</td> <td>3</td> <td>0.6 = \frac{3}{5}</td> <td>3 \frac{3}{5}</td> </tr> <tr> <td>4.75</td> <td>4</td> <td>0.75 = \frac{3}{4}</td> <td>4 \frac{3}{4}</td> </tr> <tr> <td>1.2</td> <td>1</td> <td>0.2 = \frac{1}{5}</td> <td>1 \frac{1}{5}</td> </tr> </table>
