(1 - 12%) × 875 = ? Number 875 decreased by 12% (12 percent) of its value (percentage decrease) and calculated absolute change (actual difference)
Decrease 875 by 12% 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.
12% = 12/100 = 12 ÷ 100 = 0.12.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 12% of its value.
Percentage decrease = 12% × 875
New value = 875 - Percentage decrease
Calculate the New Value
New value =
875 - Percentage decrease =
875 - (12% × 875) =
875 - 12% × 875 =
(1 - 12%) × 875 =
(100% - 12%) × 875 =
88% × 875 =
88 ÷ 100 × 875 =
88 × 875 ÷ 100 =
77,000 ÷ 100 =
770
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 875 =
770 - 875 =
- 105
Proof.
Calculate percentage increase...
... And see if we get as a result
the absolute change (actual difference).
Percentage decrease =
12% × 875 =
12 ÷ 100 × 875 =
12 × 875 ÷ 100 =
10,500 ÷ 100 =
105
So we have proven that the calculations are correct.
For positive numbers
Absolute change (actual difference) =
- 1 × Percentage decrease
Answer:
875 decreased by 12% = 770
Absolute change (actual difference):
770 - 875 = - 105
Signs: % percent, ÷ divide, × multiply, = equal, ≈ approximately equal, / fraction bar;
Writing numbers: comma ',' as thousands separator; point '.' as a decimal mark;

Decrease numbers by percentages of their values and calculate the absolute percentage change (difference)
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.
