Step-by-step solution for: Decimal Subtraction Worksheets
Absolutely! Let’s solve each of the 24 decimal subtraction problems step by step. The key is to line up the decimal points and subtract digit by digit, borrowing when necessary — just like with whole numbers, but keeping track of the decimal place.
---
1. Align the decimal points vertically.
2. Add trailing zeros if needed to make the numbers have the same number of decimal places.
3. Subtract from right to left, borrowing as needed.
4. Place the decimal point in the answer directly below the others.
