Step-by-Step Solution

To solve the addition problem of $1.54 + 0.27$ , we start by aligning the numbers by their decimal points:

Step 1: Write the numbers vertically, one under the other, ensuring that the decimal points are aligned:
$\begin{array}{c} ~~~1.54 \\ +0.27 \\ \hline \end{array}$
Step 2: Add the digits starting from the rightmost column (hundredths place):
- Hundredths place: $4 + 7 = 11$ . Write down $1$ and carry over $1$ to the tenths place.
- Tenths place: $5 + 2 = 7$ plus the carried over $1$ gives us $8$ . Write down $8$ .
- Ones place: $1 + 0 = 1$ . Write down $1$ .
Step 3: Combine the results:
$\begin{array}{c} ~~~1.54 \\ + 0.27 \\ \hline ~~~1.81 \\ \end{array}$

Therefore, the sum of $1.54$ and $0.27$ is $1.81$ .

From the given answer choices, the correct answer is choice 1: $1.81$ .
