(1 - (- 3%)) × 75 = ? Number 75 decreased by - 3% (- 3 percent) of its value (percentage decrease) and calculated absolute change (actual difference)
Decrease 75 by - 3% 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.
- 3% = - 3/100 = - 3 ÷ 100 = - 0.03.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by - 3% of its value.
Percentage decrease = - 3% × 75
New value = 75 - Percentage decrease
Calculate the New Value
New value =
75 - Percentage decrease =
75 - (- 3% × 75) =
75 + 3% × 75 =
(1 + 3%) × 75 =
(100% + 3%) × 75 =
103% × 75 =
103 ÷ 100 × 75 =
103 × 75 ÷ 100 =
7,725 ÷ 100 =
77.25
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 75 =
77.25 - 75 =
2.25
Proof.
Calculate percentage increase...
... And see if we get as a result
the absolute change (actual difference).
Percentage decrease =
- 3% × 75 =
- 3 ÷ 100 × 75 =
- 3 × 75 ÷ 100 =
- 225 ÷ 100 =
- 2.25
So we have proven that the calculations are correct.
For positive numbers
Absolute change (actual difference) =
- 1 × Percentage decrease
Answer:
75 decreased by - 3% = 77.25
Absolute change (actual difference):
77.25 - 75 = 2.25
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.
