Solve Decimal Subtraction: Finding 47.5 - 3.5

To solve the problem of finding $47.5 - 3.5$, we will follow these steps:

• Step 1: Write the numbers vertically, aligning them by the decimal point.
• Step 2: Subtract each digit starting from the right (tenths place) and moving left, borrowing where necessary.

Let's perform these steps:

Step 1: Write the numbers aligned by the decimal point:
  $47.5$
-   $3.5$
————

Step 2: Subtract the digits starting from the tenths place:
- Tenths place: $5 - 5 = 0$
- Units place: $7 - 3 = 4$
- Tens place: $4 - 0 = 4$
This results in $44.0$. Since decimal points don't alter when .0 is at the end, $44.0$ is equal to $44$.

Therefore, the solution to the problem is $44$.
