how do I calculate the percentage increase or decrease between two numbers?
Increase
[Greater Number - Lesser Number] / Lesser Number = fraction.....convert to decimal value.........then, move the decimal two places to the right and add the % sign
Decrease
[Greater Number - Lesser Number] / Greater Number = decimal value.....convert to decimal value......then, move the decimal two places to the right and add the % sign
Example: Find the pct decrease from 5 to 4
[5 - 4] / 5 = 1/5 = .20 = 20% decrease
