To determine a percentage decrease, ascertain the actual decrease, then divide this by the base number and multiply the result by 100. Decrease = a - b The base number (the number on which the decrease is based) = a Therefore, the percentage decrease = 100 x (a - b)/a % EXAMPLE : What is the percentage decrease of 15 to 11. Decrease = 15 - 11 = 4 : Base number = 15 Percentage decrease = 100 x 4/15 = 262/3 or 26.67%
To find the percentage of a number, multiply the original number by (the number of percent divided by 100). So, in this instance:15 percent of 7000 is equal to (15 / 100) = 0.15 x 7,000 = 1,050.To find percentage decrease of a number, subtract (the number of percentage decrease divided by 100) from the number 1, and multiply the resulting decimal number by the original number.15 percent off 7000 is equal to (1 - 0.15) = 0.85 x 7,000 = 5,950.
A percent of decrease (percentage decrease) is when a value is reduced by a percentage of its original amount. e.g. 100 decreased by 15 percent is 85.
