Explanation Given Information: The expression is, “ 25 decreased by 40 % ”. Consider that the original value or the base is 25 and rate of decrease is 40 % . As the rate of change is a decrease, so subtract that change from 100 % so as to compute the rate, R = 100 % − 40 % = 60 % Here, portion is missing. The formula to compute portion is P = B × R
