Calculate relative percentage decrease change from the initial (original, reference) value 102 to the new one, 105 and the absolute change (actual difference)

Relative percentage decrease change from the original number 102 to the new value of 105?

(102 - 105)/|102| =


- 3/102 =


- 3/102 × 100/100 =


(- 3 × 100 ÷ 102)/100 =


(- 300 ÷ 102)% ≈


- 2.941176470588% ≈


- 2.94%;

Relative percentage decrease is negative, so we actually have a relative percentage increase.

Answer:
:: written in two ways ::

Relative percentage decrease change from the original number 102 to the new value of 105:

Rounded to 12 decimals ≈ - 2.941176470588%
Rounded to maximum 2 decimals ≈ - 2.94%

Relative percentage change (decrease or increase)

Absolute change (actual difference):

  • The difference between two numerical quantities, y - x, is called absolute difference, actual change or actual difference.
  • When y value is a reference value (the starting value that the value x is compared to) then the difference between y and x is called the absolute change.
  • The actual difference or the actual change between two values is not always a good way to compare two numbers.
  • The actual change of one unit between numbers 3 and 2 is of much more significance than the same difference of one unit between the much larger numbers of 9,999,999,999 and 9,999,999,998.
  • In this case we need to take into account the "size" of the quantities involved.

Relative change (increase or decrease) from a number x to another number y

  • Relative change (from x to y) = (Absolute change from x to y) / |x| = (y - x) / |x|, where x is the reference value that y is being compared to and |x| is the positive value of x.
  • For values y larger than the reference value x, the relative change is a positive number, and in this case we have a relative increase.
  • For values y that are smaller than the reference x value, the relative change is negative, and in this case we have a relative decrease.
  • The relative change is not defined if the reference value is zero, y = 0.

Relative percentage change

  • Relative percentage change is the relative change calculated as a percentage;
  • Relative percentage change = Relative change × 100/100 = (Relative change × 100)%.

Examples of calculating the relative percentage change (increase or decrease)

  • Relative change (from 3 to 2) = (2 - 3) / |3| = -1/3 = -0.33 = -33%; this change is a relative percentage decrease;
  • Relative change (from 9.999.999.999 to 9.999.999.998) = (9.999.999.998 - 9.999.999.999) / |9.999.999.999| = -1/9.999.999.999 ≈ 0 = 0%;
  • Relative change (from -3 to 2) = (2 - (-3)) / |-3| = (2 + 3) / 3 = 5/3 = 1.67 = 167%; this change is a relative percentage increase;
  • Relative change (from -9.999.999.999 to 9.999.999.998) = (9.999.999.998 - (-9.999.999.999)) / |-9.999.999.999| = 19.999.999.997/9.999.999.999 ≈ 2 = 200%; this change is a relative percentage increase;
  • Relative change (from 3 to -2) = (-2 - 3) / |3| = -5/3 = -1.67 = -167%; this change is a relative percentage decrease;
  • Relative change (from 9.999.999.999 to - 9.999.999.998) = (-9.999.999.998 - 9.999.999.999) / |9.999.999.999| = -19.999.999.997/9.999.999.999 ≈ -2 = -200%; this change is a relative percentage decrease.
