Final answer:
To find the sum of 3.4 and 8.17, you simply add the two numbers together, aligning the decimal points, to get a result of 11.57.
Step-by-step explanation:
The sum of 3.4 and 8.17 is calculated by simply adding the two numbers together.
- First, write down the numbers so that the decimal points are aligned:
- 3.4
- + 8.17 Then add each column, starting from the rightmost column: Add the hundredths place (4 + 7 = 11), write down 1 and carry over 1 to the tenths place. Add the tenths place along with the carried over 1 (1 + 9 = 10), write down 0 in the tenths place and carry over 1 to the ones place. Add the ones place along with the carried over 1 (3 + 8 + 1= 12). This gives us the final sum of 11.57. Therefore, the correct answer is 11.57.
