Number 60 decreased by 13% (13 percent) of its value (percentage decrease) and calculated absolute change (actual difference)

Decrease 60 by 13% 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.


13% = 13/100 = 13 ÷ 100 = 0.13.


100% = 100/100 = 100 ÷ 100 = 1.


Decrease number by 13% of its value.

Percentage decrease = 13% × 60


New value = 60 - Percentage decrease


Calculate the New Value

New value =


60 - Percentage decrease =


60 - (13% × 60) =


60 - 13% × 60 =


(1 - 13%) × 60 =


(100% - 13%) × 60 =


87% × 60 =


87 ÷ 100 × 60 =


87 × 60 ÷ 100 =


5,220 ÷ 100 =


52.2


Calculate absolute change (actual difference)

Absolute change (actual difference) =


New value - 60 =


52.2 - 60 =


- 7.8


Proof.

Calculate percentage increase...

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

Percentage decrease =


13% × 60 =


13 ÷ 100 × 60 =


13 × 60 ÷ 100 =


780 ÷ 100 =


7.8


So we have proven that the calculations are correct.

For positive numbers


Absolute change (actual difference) =


- 1 × Percentage decrease


Answer:
60 decreased by 13% = 52.2
Absolute change (actual difference):
52.2 - 60 = - 7.8

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:

60 decreased by 12% = ?


60 decreased by 14% = ?


60 decreased by 1% = ?

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.
