Method 1: The Decimal Shift
This is the simplest and most direct way to find 10% of a number:
- Take the original number.
- Move the decimal point one place to the left.
Example:
Find 10% of 500.
Move the decimal one place to the left: 500 becomes 50.0
Therefore, 10% of 500 is 50.
Another Example:
Find 10% of 75.
Move the decimal one place to the left: 75 becomes 7.5
Therefore, 10% of 75 is 7.5.
Method 2: Division by 10
This method is mathematically equivalent to the decimal shift:
- Take the original number.
- Divide it by 10.
Example:
Find 10% of 230.
Divide 230 by 10: 230 / 10 = 23
Therefore, 10% of 230 is 23.
