Finding 5 percent of a number

1. Choose a large number (or sum of money).
2. Move the decimal point one place to the left.
3. Divide by 2 (take half of it).

   Example:

1. If the amount of money selected is $850:
2. Move the decimal point one place to the left.: 85
3. Divide by 2: 85/2 = 42.50
4. So 5% of $850 = $42.50.

   See the pattern?

1. If the amount of money selected is $4500:
2. Move the decimal point one place to the left.: 450
3. Divide by 2: 450/2 = 225
4. So 5% of $4500 = $225.
