The correct Answer is:
To solve the question \( 89.1 + 2.2 \), follow these steps: ### Step 1: Write the numbers vertically Align the numbers so that the decimal points are in line with each other. ``` 89.1 + 2.2 ``` ### Step 2: Add the numbers starting from the right Begin adding from the rightmost column (the tenths place): - **Tenths place**: \( 1 + 2 = 3 \) ``` 89.1 + 2.2 ------- 3 (tenths place) ``` ### Step 3: Move to the units place Next, add the numbers in the units place: - **Units place**: \( 9 + 2 = 11 \) Write down 1 and carry over 1 to the next column (the tens place). ``` 89.1 + 2.2 ------- 1 (units place, carry over 1) ``` ### Step 4: Add the tens place Now, add the numbers in the tens place: - **Tens place**: \( 8 + 0 + 1 (carry) = 9 \) ``` 89.1 + 2.2 ------- 91 (tens place) ``` ### Step 5: Combine the results Now combine all the results: ``` 89.1 + 2.2 ------- 91.3 ``` ### Final Answer Thus, \( 89.1 + 2.2 = 91.3 \). ---
