Solve Decimal Addition: 0.6 + 0.5 Using Number Blocks

To solve this problem, we'll follow these steps:

• Step 1: Align the numbers $0.6$ and $0.5$ by their decimal points.
• Step 2: Add the numbers as you would do with whole numbers.
• Step 3: Place the decimal point in the sum directly under the decimal points of the addends.

Now, let's work through each step:
Step 1: Write the numbers aligned by the decimal point:
     0.6
+ 0.5
Step 2: Add the digits: - Start from the right: $6 + 5 = 11$. Place a $1$ in the tenths column and carry over $1$.
Step 3: Add the whole number part considering any carry: - $0 + 0 + 1$ (from the carry) = $1$.

The sum of $0.6$ and $0.5$ gives $1.1$.

Therefore, the solution to the problem is $1.1$.
