and if it is a percentage of decrease, we will subtract: 80 - 20 = 60, so we will obtain that 80 decreased by 25% is 60. knowing this, we should point out that there is a shortcut to do these operations, which may help us (a lot!) to speed up our calculations. we can use the reference to the unit (1) instead of the traditional 100%, so, to increase a number by 25%, we add: 1 + 0.25 = 1.25 (mentally, so we save time) and then we apply it to our initial amount: 80 * 1.25 = 100 getting the same result above mentioned but in only one arithmetical operation (one multiplication). in the same way, to decrease a number by 25%, we subtract: 1 - 0.25 = 0.75 (mentally again) and again we apply it to our initial amount: 80 * 0.75 = 60 using this method, you will save valuable time, reducing the operations that you have to perform and, sometimes, your need of the calculator. i recommend starting with 'easy' percentages and round numbers, both multiplying and dividing (you can use the calculator when you need it), to see for yourself their effect on the figures. for example: to increase and decrease 200 by 25% 200 * 1.25 = 250 200 * 0.75 = 150 10
