(1 - (- 11%)) × 0.036 = ? Number 0.036 decreased by - 11% (- 11 percent) of its value (percentage decrease) and calculated absolute change (actual difference)

Decrease 0.036 by - 11% of its value

Detailed calculations & verification

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':


p% = p 'out of one hundred',


p% is read p 'percent',


p% = p/100 = p ÷ 100.


- 11% = - 11/100 = - 11 ÷ 100 = - 0.11.


100% = 100/100 = 100 ÷ 100 = 1.


Decrease number by - 11% of its value.

Percentage decrease = - 11% × 0.036


New value = 0.036 - Percentage decrease


Calculate the New Value

New value =


0.036 - Percentage decrease =


0.036 - (- 11% × 0.036) =


0.036 + 11% × 0.036 =


(1 + 11%) × 0.036 =


(100% + 11%) × 0.036 =


111% × 0.036 =


111 ÷ 100 × 0.036 =


111 × 0.036 ÷ 100 =


3.996 ÷ 100 =


0.03996 ≈


0.04


Calculate absolute change (actual difference)

Absolute change (actual difference) =


New value - 0.036 =


0.03996 - 0.036 =


0.00396 ≈


0


Proof.

Calculate percentage increase...

... And see if we get as a result
the absolute change (actual difference).

Percentage decrease =


- 11% × 0.036 =


- 11 ÷ 100 × 0.036 =


- 11 × 0.036 ÷ 100 =


- 0.396 ÷ 100 =


- 0.00396 ≈


0


So we have proven that the calculations are correct.

For positive numbers


Absolute change (actual difference) =


- 1 × Percentage decrease


Answer:
:: written in two ways ::

Not rounded:
0.036 decreased by - 11% = 0.03996
Absolute change (actual difference):
0.03996 - 0.036 = 0.00396


Rounded to maximum 2 decimals:
0.036 decreased by - 11% ≈ 0.04
Absolute change (actual difference):
0.04 - 0.036 ≈ 0

Signs: % percent, ÷ divide, × multiply, = equal, ≈ approximately equal, / fraction bar;

Writing numbers: comma ',' as thousands separator; point '.' as a decimal mark;

More operations of this kind:

0.036 decreased by - 12% = ?


0.036 decreased by - 10% = ?


0.036 decreased by 1% = ?

Decrease number by percentage of value, calculate percentage decrease

How to calculate the new value of a number by decreasing it by percentage of its value and the absolute percentage change (difference)

  • Percentage decreased number = Initial value - Absolute percentage change (difference)
  • Absolute percentage change (difference) = Percentage decrease % × Initial value
  • Percentage decreased number = Initial value - Percentage decrease % × Initial value = (1 - Percentage decrease %) × Initial value
  • In conclusion:

    Percentage decreased number = (1 - Percentage decrease %) × Initial value

    Initial value = Percentage decreased number / (1 - Percentage decrease %)

    Absolute percentage change (difference) = Percentage decrease % × Initial value = New value - Initial value

Examples of calculations on how to decrease a number by percentage of its value and calculate the absolute percentage change:

  • If Percentage decrease % = 20%, (1 - Percentage decrease %) = 1 - 20% = 100/100 - 20/100 = 80/100 = 0.8 => Percentage decreased number = 0.8 × Initial value, and Initial value = Percentage decreased number / 0.8; Absolute percentage change (difference) = New value - Initial value;
  • If Percentage decrease % = 5%, (1 - Percentage decrease %) = 1 - 5% = 100/100 - 5/100 = 95/100 = 0.95 => Percentage decreased number = 0.95 × Initial value, and Initial value = Percentage decreased number / 0.95; Absolute percentage change (difference) = New value - Initial value;
  • If Percentage decrease % = 120%, (1 - Percentage decrease %) = 1 - 120% = 100/100 - 120/100 = -20/100 = -0.2 => Percentage decreased number = -0.2 × Initial value, and Initial value = Percentage decreased number / -0.2; Absolute percentage change (difference) = New value - Initial value;
  • If Percentage decrease % = -30%, (1 - Percentage decrease %) = 1 - (-30%) = 1 + 30% = 100/100 + 30/100 = 130/100 = 1.3 => Percentage decreased number = 1.3 × Initial value, and Initial value = Percentage decreased number / 1.3; this is in fact a percentage increase of the initial number; Absolute percentage change (difference) = New value - Initial value.
