To convert the mixed number 2 2/8 into decimal form, we first need to understand what a mixed number is. A mixed number is a whole number combined with a proper fraction. In this case, 2 2/8 consists of the whole number 2 and the fraction 2/8.

Step-by-Step Conversion Process

Step 1: Convert the Fraction to Decimal

First, we will convert the fraction part 2/8 into decimal form. To do this, we divide the numerator (2) by the denominator (8).

[ \text{Decimal} = \frac{2}{8} = 0.25 ]

Step 2: Add the Decimal to the Whole Number

Next, we need to add the decimal obtained from the fraction to the whole number part of the mixed number.

[ \text{Total} = 2 + 0.25 = 2.25 ]

So, 2 2/8 converts to 2.25 in decimal form.

Summary of the Process

The overall conversion can be summarized in the following table:

<table> <tr> <th>Step</th> <th>Calculation</th> <th>Result</th> </tr> <tr> <td>1</td> <td>Convert 2/8 to decimal</td> <td>0.25</td> </tr> <tr> <td>2</td> <td>Add the whole number</td> <td>2 + 0.25 = 2.25</td> </tr> </table>

Important Note

When converting fractions to decimals, it's helpful to remember that:

  • The fraction part can always be expressed in decimal form by performing a simple division.
  • Always add the decimal result to the whole number part of the mixed number.

Further Examples

Let’s look at a few more examples of converting mixed numbers to decimal to solidify your understanding.
