Solve Decimal Addition: 6.2 + 2.4 Step-by-Step

$6.2+2.4=$

To solve this problem, we follow these steps:

• Step 1: Write down the numbers vertically, aligning the decimal points.
• Step 2: Add each column of digits, starting from the rightmost column (the tenths place).
• Step 3: If any column adds to a number equal to or greater than 10, carry over to the next left column.

Let's work through the solution:
Step 1: Align the numbers vertically:
6.2
+ 2.4
--------
Step 2: Add the digits in the tenths column: $2 + 4 = 6$. Write the 6 in the tenths place below.
Step 3: Add the digits in the ones column: $6 + 2 = 8$. Write the 8 in the ones place below.
Therefore, the sum of $6.2$ and $2.4$ is $8.6$.

Therefore, the solution to the problem is $8.6$, which corresponds to choice 1.
