(1 - 1%) × 105 = ? Number 105 decreased by 1% (1 percent) of its value (percentage decrease) and calculated absolute change (actual difference)

Decrease 105 by 1% 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.

1% = 1/100 = 1 ÷ 100 = 0.01.

100% = 100/100 = 100 ÷ 100 = 1.


Decrease number by 1% of its value.

Percentage decrease = 1% × 105

New value = 105 - Percentage decrease


Calculate the New Value

New value =

105 - Percentage decrease =

105 - (1% × 105) =

105 - 1% × 105 =

(1 - 1%) × 105 =

(100% - 1%) × 105 =

99% × 105 =

99 ÷ 100 × 105 =

99 × 105 ÷ 100 =

10,395 ÷ 100 =

103.95


Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 105 =

103.95 - 105 =

- 1.05


Proof.

Calculate percentage increase...

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

Percentage decrease =

1% × 105 =

1 ÷ 100 × 105 =

1 × 105 ÷ 100 =

105 ÷ 100 =

1.05


So we have proven that the calculations are correct.

For positive numbers

Absolute change (actual difference) =

- 1 × Percentage decrease


Answer:
105 decreased by 1% = 103.95
Absolute change (actual difference):
103.95 - 105 = - 1.05

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:

105 decreased by 0% = ?

105 decreased by 2% = ?

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.
