Complete the Decimal Expression: Finding the Value of 8.1 =

To solve this problem, we need to convert the decimal number $8.1$ into a mixed number.

• Step 1: Recognize that the number $8.1$ can be broken into an integer part and a fractional part. The integer part is $8$ and the decimal part is $0.1$.
• Step 2: Convert the decimal part $0.1$ into a fraction. Since $0.1$ is equivalent to $\frac{1}{10}$, we write $0.1 = \frac{1}{10}$.
• Step 3: Combine the integer part and the fractional part to form a mixed number. Thus, $8.1$ can be rewritten as $8 + \frac{1}{10}$ which simplifies to the mixed number $8 \frac{1}{10}$.

Therefore, the solution to the problem is $8 \frac{1}{10}$.
