Before diving into the conversion, let's ensure we're on the same page regarding what these numbers are:

• Decimal: A decimal number represents a whole and a fractional part separated by a decimal point. For instance, 8.21 has a whole number part (8) and a decimal part (.21).

• Mixed Number: This is a combination of a whole number and a proper fraction, where the whole number comes first, followed by a fraction, like 4 1/4.

The goal is to convert 8.21 to a number that consists of both a whole number and a fraction. Here's how we do it:

Step 1: Separate the Whole and Decimal Part

To start, we need to separate 8 from .21:

• Whole Number: 8
• Decimal Part: .21

Step 2: Convert the Decimal to a Fraction

Let's look at .21:

• .21 as a fraction is 21/100 since moving the decimal point two places to the right gives us a denominator of 100.

Step 3: Simplify the Fraction

The fraction 21/100 can be simplified by finding the greatest common divisor (GCD) of 21 and 100, which is 1. Therefore, the simplified fraction is:

• 21/100

Step 4: Combine Whole and Fraction

Now, we put it all together:

• Whole Number: 8
• Fraction: 21/100

So, the mixed number form of 8.21 is:

8 21/100
