Calculate the result of a number that has decreased in percentage, by subtracting 100 with the percent number, then dividing it by 100, and multiply it by the number.
Formula:
Decrease X percent of Y is equal to Z
Z = Y x [( 100 - X ) ÷ 100 ]
Example:
Decrease 5% of 50
50 x [( 100 - 5 ) ÷ 100 ] = 47.5
