Finding 5 percent of a number
Choose a large number (or sum of money).
Move the decimal point one place to the left.
Divide by 2 (take half of it).
Example:
If the amount of money selected is $850:
Move the decimal point one place to the left.: 85
Divide by 2: 85/2 = 42.50
So 5% of $850 = $42.50.
See the pattern?
If the amount of money selected is $4500:
Move the decimal point one place to the left.: 450
Divide by 2: 450/2 = 225
So 5% of $4500 = $225.
