Answer:
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.
30% = 30/100 = 30 ÷ 100 = 0.3.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 30% of its value.
Calculate the New Value
New value =
12 + Percentage increase =
12 + (30% × 12) =
12 + 30% × 12 =
(1 + 30%) × 12 =
(100% + 30%) × 12 =
130% × 12 =
130 ÷ 100 × 12 =
130 × 12 ÷ 100 =
1,560 ÷ 100 =
15.6
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 12 =
15.6 - 12 =
3.6
