Solve the Decimal Subtraction: 15.6 - 0.3

$15.6-0.3=$

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

• Step 1: Align the decimal numbers vertically, ensuring that the decimal points are perfectly aligned.
• Step 2: Subtract the numbers starting from the rightmost digit (the tenths place in this case).
• Step 3: Write the result directly below, keeping the decimal point aligned in the final answer.

Now, let's work through each step:

Step 1: We have the numbers $15.6$ and $0.3$. Align these two numbers:

  15.6
-  0.3
------

Step 2: Start the subtraction from the rightmost digit. Subtract $0.3$ from $15.6$. The tenths place: $6 - 3 = 3$.

In the units place, we then directly bring down the 15, as there is no need to subtract anything further.

  15.6
-  0.3
------
  15.3

Step 3: Ensure the result is aligned with a decimal point directly below the original decimal points: the result is $15.3$.

Therefore, the solution to the problem is $15.3$.
