Understanding 8.21 As A Mixed Number: A Step-By-Step Guide

To understand the concept of mixed numbers, let’s take a closer look at the decimal 8.21 and how we can convert it into a mixed number. A mixed number consists of a whole number and a proper fraction, and converting a decimal to a mixed number is an essential skill in mathematics. In this article, we will break down the steps involved in this conversion, explain each step clearly, and provide you with tips to make the process easier.

Step 1: Identify the Whole Number

The first step in converting 8.21 into a mixed number is to identify the whole number part of the decimal. The whole number is the integer part before the decimal point.

• For 8.21, the whole number is 8.

This means that our mixed number will start with 8 as the whole number.

Step 2: Separate the Decimal Part

Next, we need to focus on the decimal part of the number. For 8.21, the decimal part is 0.21.

• This decimal will be converted into a fraction in the next steps.

It's essential to note that separating the whole number from the decimal is a crucial step as it will guide you in forming the mixed number.

Step 3: Convert the Decimal to a Fraction

Now, let's convert the decimal part (0.21) into a fraction. The decimal 0.21 can be expressed as:

• 21/100 (since there are two digits after the decimal).

This fraction is already in its simplest form, as there are no common factors between the numerator and the denominator.

Step 4: Combine the Whole Number with the Fraction

With the whole number identified as 8 and the decimal converted to the fraction 21/100, the next step is to combine these two parts to form a mixed number.

• Therefore, 8.21 as a mixed number is 8 21/100.

This mixed number accurately represents the original decimal in a different form.
