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.
0% = 0/100 = 0 ÷ 100 = 0.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 0% of its value.
Percentage decrease = 0% × 12,342
New value = 12,342 - Percentage decrease
Calculate the New Value
New value =
12,342 - Percentage decrease =
12,342 - (0% × 12,342) =
12,342 - (0 ÷ 100 × 12,342) =
12,342 - (0 × 12,342) =
12,342 - 0 =
12,342
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 12,342 =
12,342 - 12,342 ≈
0
Proof.
Calculate percentage increase...
... And see if we get as a result
the absolute change (actual difference).
Percentage decrease =
0% × 12,342 =
0 ÷ 100 × 12,342 =
0 × 12,342 ÷ 100 =
0 ÷ 100 =
0
So we have proven that the calculations are correct.
For positive numbers
Absolute change (actual difference) =
- 1 × Percentage decrease
Answer:
12,342 decreased by 0% ≈ 12,342
Absolute change (actual difference):
12,342 - 12,342 ≈ 0
